International Terrorism Using Toxic Chemicals as an Element of Hybrid Warfare

Modern terrorism is a complex system that consists of a complex of complementary processes – ideological, criminal, military, political, religious and nationalistic. Chemical terrorism is one of the elements of hybrid warfare – a new technology in the fight for the reorganization of the world at the present stage. The purpose of this article is to consider one of the elements of hybrid wars – chemical terrorism. Sources and informational basis of the research, methodology. In this work, the sources published by the Organization for the Prohibition of Chemical Weapons (OPCW) were used. The publications available through the databases PubMed, Google Scholar, eLibrary, etc. were also studied. Research method – system analysis. The probability of the use of chemical warfare agents and toxic chemicals by terrorists of various ideological orientations as part of a hybrid war strategy has been studied. The discussion of the results. Hybrid military conflicts of a non-classical nature involve the participation of international terrorist organizations in hostilities. The Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction (CWC) does not explicitly prohibit non-state actors from obtaining and using chemical weapons. This situation is very convenient for the states that have signed the CWC and use terrorist organizations as part of the strategy of indirect action. In such cases the information and psychological operations are aimed at the collapse and fragmentation of countries, undermining their ability to resist, discrediting their leaders, and causing a split in the ranks of the allies. This was most clearly shown in the incidents with the use of toxic chemicals in Syria. Conclusion. Working groups under the auspices of the UN and the OPCW, sent to Syria to investigate incidents with the use of sarin, proved unable to conduct objective investigations. They usually ended up on the side of the sponsors of chemical terrorist attacks, despite the evidence of falsification. This, in turn, can lead to serious military conflicts, for which the role of casus belli will be played by false news from the global media. The only mechanism that made it possible to stop such provocations in Syria was a public warning from the Russian side about the place and time of the planned false flag attack. At the same time, such a selective position of the UN and the OPCW can at any moment lead to the loss of the control over chemical weapons in certain regions of the world.

Simulation Model of Required Pre-deployed Auto-injectors and Stockpiled Antidotes against Chemical Terrorism

Introduction:Chemical terrorist attacks using nerve gas require patients with immediate administration of antidote, or otherwise they will experience abnormal neurological activity, respiratory arrest, and death. When it occurs in large stadiums at mass gatherings such as the Olympics, under normal medical care systems, preventable deaths occur due to insufficient deployment of on-site auto-injectors and stockpiled antidotes in hospitals. In Japan, the government has stockpiled antidotes in confidential warehouses and deployed auto-injectors around possible terrorist sites. When a chemical attack occurs, a stockpile of antidotes go to hospitals, auto-injectors go to the site, and firefighters and police are allowed to administer auto-injectors to patients. However, few studies are conducted on pre-deployment of auto-injectors and antidotes in chemical terrorisms. Therefore, the number of pre-deployment was examined.Method:A single chemical attack with 750 patients was assumed. Response was divided into five steps: (1) transportation of stockpiles to hospitals, (2) transportation of auto-injectors to the site, (3) on-site use of auto-injectors, (4) transportation of patients to hospitals, and (5) patient care in hospitals. Computer estimation was used for the time required for transportation for (1), (2), and (4). Desktop exercises were conducted for on-site response time, outpatient response time, and the number of beds available at hospitals for (3) and (5). The values obtained from computer estimation and desktop exercises were imported into the simulation model to measure the number of paramedics, auto-injectors required to be deployed in advance, and the amount of stockpiles required to be delivered to hospitals.Results:A minimum of 80 auto-injectors and ten paramedics were required to be pre-positioned at the scene. A minimum of 100 ampules of antidote was required immediately at the nearest hospitals.Conclusion:The pre-deployment of auto-injectors and personnel are essential to reduce the number of deaths in the event of chemical terrorisms.

АНАЛИЗ РИСКОВ СОВЕРШЕНИЯ МЕЖДУНАРОДНЫМИ ТЕРРОРИСТАМИ ХИМИЧЕСКИХ ТЕРРОРИСТИЧЕСКИХ АКТОВ И МЕРЫ ПРОТИВОДЕЙСТВИЯ ИМ

The urgency of the problem of possible chemical terrorist acts by international terrorists is now becoming increasingly important, since there are quite good reasons for this. In this regard, the author conducted a study of the danger that comes from terrorist acts committed by international terrorists using chemical components. In the process of analyzing the risks of committing chemical terrorist at-tacks, the author found that among the main tasks of international terrorist organizations when committing terrorist attacks is not only causing material damage, but the formation of a public resonance about this, and besides Moreover, these attacks are accompanied by numerous human casualties. In this regard, the author draws conclusions that the subjects of law enforcement activities must have special skills and abilities, and quickly solve various problem situations that arise during the imple-mentation of acts of chemical terrorism. In particular, in this work, a special role should be assigned to joint coordinated actions for planning and carrying out measures in the process of eliminating the consequences of chemical terrorist attacks. In the course of the study, the author convincingly proved that the prevention of acts of chemical terrorism should be carried out on the basis of a sys-tematic approach and coordination of the activities of the concerned services. It is also important in this area to carry out preventive measures in the field of training and advanced training of personnel. The author also focuses on the fact that comprehensive professional and applied training will serve as the basis for increasing the knowledge and skills of the subjects of the fight against terrorism, and will also allow the formation of the whole complex of specialized competencies of specialists necessary for performing professional tasks in the field of combating chemical terrorism. The results obtained can be used in further work on counteracting acts of chemical terrorism, in the system of pro-fessional training of internal affairs bodies of the Ministry of Internal Affairs of Russia, as well as in the educational process of higher educational institutions of a legal profile.

Assessment of the effectiveness of a course in major chemical incidents for front line health care providers: a pilot study from Saudi Arabia

BackgroundMass chemical exposure emergencies are infrequent but can cause injury, illness, or loss of life for large numbers of victims. These emergencies can stretch and challenge the available resources of healthcare systems within the community. Political unrest in the Middle East, including chemical terrorist attacks against civilians in Syria and increasing chemical industry accidents, have highlighted the lack of hospital preparedness for chemical incidents in the region. This study aimed to evaluate the effectiveness of a course designed to empower frontline healthcare providers involved in mass casualty incidents with the basic knowledge and essential operational skills for mass chemical exposure incidents in Saudi Arabia.MethodsA mixed-methods approach was used to develop a blended learning, simulation enhanced, competency-based course for major chemical incidents for front line healthcare providers. The course was designed by experts from different disciplines (disaster medicine, poisoning / toxicology, and Hazard Material Threat - HAZMAT team) in four stages. The course was piloted over five days at the Officers Club of the Ministry of Interior (Riyadh, Saudi Arabia). The 41 participants were from different government health discipline sectors in the country. Pre- and post-tests were used to assess learner knowledge while debriefing sessions after the decontamination triage session and simulation-enhanced exercises were used for team performance assessment.ResultsThe overall knowledge scores were significantly higher in the post-test (69.47%) than the pre-test (46.3%). All four knowledge domains also had significant differences between pre- and post-test results. There were no differences in the pre and post-test scores for healthcare providers from the different health disciplines. A one-year post-event survey demonstrated that participants were satisfied with their knowledge retention. Interestingly, 38.3% had the opportunity to put this knowledge into practice in relation to mass chemical exposure incidents.ConclusionDelivering a foundation level competency-based blended learning course with enhanced simulation training in major chemical incidents for front line healthcare providers may improve their knowledge and skills in response to such incidents. This in turn can improve the level of national preparedness and staff availability and make a crucial difference in reducing the health impacts among victims.

Parallel Coupling of Ion Mobility Spectrometry and Ion Trap Mass Spectrometry for the Real-Time Alarm Triggering and Identification of Hazardous Chemical Leakages.

Hazardous chemical leakages involved in chemical terrorist attacks and chemical industrial accidents have been posing severe threats to human health and the environment. Vehicle-mounted mass spectrometry (MS) has been developed for continuous, on-road measurements to map the spatial and temporal distributions of hazardous chemicals. However, the detection of chemicals with small temporal scales and spatial scales is always challenging. In this study, a parallel coupling apparatus combining the techniques of ion mobility spectrometry and ion trap MS (p-IMS-ITMS) was developed to improve the detection rate and the time response capability of a stand-alone ITMS system for short time-span chemical tracking. A workflow was also proposed along with the apparatus, where the ITMS system can be triggered, as chemical suspects were discovered with the IMS system. The sampling positions of the ITMS system were investigated and optimized. In addition, a strategy was proposed to diminish the time span of samples from 1.5 to 0.5 s for evaluating the performances of the p-IMS-ITMS system. The detection rate of the stand-alone ITMS system was measured to be only 9.5, 32, and 87.5% for the time span of 0.5, 1, and 1.5 s, respectively. By comparison, the detection rates of the p-IMS-ITMS system were 99.5, 100, and 100%, where the detection rate was increased by a factor of 10 for 0.5 s time span. Moreover, the addition of an IMS system could provide temporal patterns of hazardous chemicals with a resolution of 33 ms. Finally, the potential of the p-IMS-ITMS system for environmental navigation monitoring and assessment was further demonstrated by detecting the leakages of dimethyl methyl phosphonate and dipropylene glycol monomethyl ether.

Five Decades of Global Chemical Terror Attacks: Data Analysis to Inform Training and Preparedness.

Chemical weapons attacks during the recent conflict in Syria and Iraq highlight the need to better understand the changing epidemiology of chemical weapons use, especially among non-state actors. Public health professionals and policy-makers require this data to prioritize funding, training, chemical weapons preparedness, disaster response, and recovery. The purpose of this investigation is to provide descriptive data that can be used by policy-makers and public safety officials to better prepare for these potential attacks. A five-decade descriptive retrospective review of The Global Terrorism Database, maintained by the National Consortium for the Study of Terrorism and Responses to Terrorism, was conducted to understand trends in chemical agents, targets, and routes of exposure. We reviewed and analyzed data specific to these documented chemical attacks between 1970 and 2017. 383 terror attacks involved chemical weapons over the study period. A specific agent was named in 154 incidents, while 124 incidents could be classified into traditional chemical weapons categories (eg, vesicant, choking agents). A route of exposure was identified in 242 attacks, with the most common routes of exposure being dermal-mucosal and inhalational. Caustic agents were used in the highest portion of attacks (25%) where the route of exposure was known. Explosive devices were used in 21% of attacks to deliver these chemical agents. Of particular note, private citizens and educational facilities were targeted in 25% and 12% of attacks, respectively. The average number of attacks increased from 6 per year between 1970 and 2011 to 24.9 per year between 2011 and 2017 (coinciding with the start of the Syria conflict). The most commonly utilized chemicals were chlorine (26.0%), tear gas (20.8%), and cyanide (15.6%). Blood agent incidents declined from 32.6% before the September 11, 2001 attacks to 13.6% after 2001, while nerve agent attacks fell from 9.3% to 1.2%. In contrast, choking (namely chlorine) and vesicant (mustard) agent use increased from 7% to 48.1% and from 2.3% to 6.2% of attacks, respectively. Chemical weapon use in global terrorism remains an increasingly common occurrence that requires better characterization. The average number of chemical terrorist attacks per year is increasing, with a large proportion resulting from the conflicts in Iraq and Syria. Choking (chlorine) and vesicant (mustard) agents have become the predominant chemical terror agent since 2001, with a decreased incidence of blood (cyanogenic) and nerve (sarin) agents. Future preparedness initiatives should focus on vulnerable targets such as private citizens and educational institutions. Improving blast injury response is essential, along with prioritizing disaster training focused on choking agents, vesicants, and caustics.

Modeling and Risk Analysis of Chemical Terrorist Attacks: A Bayesian Network Method.

The chemical terrorist attack is an unconventional form of terrorism with vast scope of influence, strong concealment, high technical means and severe consequences. Chemical terrorism risk refers to the uncertainty of the effects of terrorist organisations using toxic industrial chemicals/drugs and classic chemical weapons to attack the population. There are multiple risk factors infecting chemical terrorism risk, such as the threat degree of terrorist organisations, attraction of targets, city emergency response capabilities, and police defense capabilities. We have constructed a Bayesian network of chemical terrorist attacks to conduct risk analysis. The scenario analysis and sensitivity analysis are applied to validate the model and analyse the impact of the vital factor on the risk of chemical terrorist attacks. The results show that the model can be used for simulation and risk analysis of chemical terrorist attacks. In terms of controlling the risk of chemical terrorist attack, patrol and surveillance are less critical than security checks and police investigations. Security check is the most effective approach to decrease the probability of successful attacks. Different terrorist organisations have different degrees of threat, but the impacts of which are limited to the success of the attack. Weapon types and doses are sensitive to casualties, but it is the level of emergency response capabilities that dominates the changes in casualties. Due to the limited number of defensive resources, to get the best consequence, the priority of the deployment of defensive sources should be firstly given to governmental buildings, followed by commercial areas. These findings may provide the theoretical basis and method support for the combat of the public security department and the safety prevention decision of the risk management department.

A Personalized and Practical Method for Analyzing the Risk of Chemical Terrorist Attacks

The chemical terrorist attack is a type of unconventional terrorism that threatens the safety of cities. This kind of terrorist attack is highly concealed and difficult to be detected. Once the attack is successful, the consequences will be severe and the scope of impact will be enormous. Therefore, public security and emergency departments need to perform risk analysis and dynamic knowledge update to reduce risk or mitigate the effects of accidents. In order to quickly and effectively analyze the risk of chemical terrorist attacks, this article proposed a hybrid approach (B-R model) to analyze the risk of chemical terrorist attacks. First, a modular and customizable Bayesian network (BN) model library was built, which can satisfy users to select multi-dimensional risk factors. Based on the personalized BN, a risk knowledge graph (RKG) is constructed with multi-source data to realize the combination of risk analysis and knowledge acquisition. Then the threat degree of terrorist organizations, the strength of defensive forces, and the risk value of targets is calculated and displayed. The BN-RKG method provides data and theoretical support for defenders' resource allocation and emergency decision-making. Finally, a case study was conducted for a hypothetical scenario analysis. The result shows that the hybrid method can help with risk control and have the potential to support practical policymaking.

Victims of chemical terrorism, a family of four who were exposed to sulfur mustard

Sulfur mustard (SM) was responsible for more than 80% of all documented chemical casualties during the Great War. Recent literature on clinic picture of SM exposure remained so limited with the sporadic cases who were accidentally exposed to SM especially either in Western Europe or China. We reported a Syrian family of four who became victims of chemical terrorism due to SM exposure and we described the detailed clinical course of the family including the medical history, initial symptomatology, clinical examination, hematological data, and initial treatment in the first 48 hours after exposure at Kilis State Hospital, Turkey. The principles of our therapeutic approaches were designed according to the total affected body surface area, severity of cutaneous and respiratory lesions, and existing hematological disorders. SM is still considered as a critical vesicant agent and a current threat because of its ease of synthesis. Chemical terrorist attacks of non-state actors or terrorist organizations with “home-made” SM is likely such a threat which is targeting health systems of developed and developing countries. Except sarin attacks in Japan, the literature depends on real incidents of chemical terrorism is so rare and for this reason we have gaps and challanges in the prepardness of medical response system against chemical terrorism. Medical management could be performed adequetly only if the response system is well planned, well equipped, and well prepared for overburdened medical facilities filled with SM contaminated casualties after a chemical terrorist attack.

The design and development of disaster medical education for medical students in curriculum Medi-cal student disaster medicine education

We aim to develop and implement a disaster medicine curriculum for medical student education, so the six-step approach to curriculum development for medical education has been used as a formal process instrument. Recognized experts in disaster health care have provided input using disaster-related physician training programs, scientific evidence if available, proposals for education by international disaster medicine organizations and their expertise as the basis for content development. The final course consists of 14 modules composed of 2-h units. The concepts of disaster medicine, including response, med-ical assistance, law, command, coordination, communication, and mass casualty management, are intro-duced. Hospital preparedness plans and experiences from worldwide disaster assistance are reviewed. Life-saving emergency and limited individual treatment under disaster conditions are discussed. Specifics of initial management of explosive, war-related, radiological/nuclear, chemical, and biological incidents empha-sizing infectious diseases and terrorist attacks are presented. An evacuation exercise is completed, and a mass casualty triage is simulated in collaboration with local disaster response agencies. Decontamination procedures are demonstrated at the local fire department, and personal decontamination practices are exer-cised. Mannequin resuscitation is practiced while personal protective equipment is utilized. An interactive review of professional ethics, stress disorders, psychosocial interventions, and quality improvement efforts complete the training. The curriculum offers medical disaster education in a reasonable time frame, interdis-ciplinary format, multi-experiential course and flexible structure. It can serve as a template for basic medi-cal student disaster edu-cation. Key words: Disasters; Medical education; Curriculum; Medical students

Preparedness of Hospitals for Response to Chemical Terrorist Incidents: Review and Recommendations

The burden of responding to chemical attacks in the event of a terrorist event will fall to local hospitals, both primary and tertiary, as well as primary care physicians. Despite this, previous efforts, including the Defense Against Weapons of Mass Destruction Act of 1996, have failed to produce such readiness. Additionally, in the wake of the September 11, 2001, terrorist attacks, and the creation of the Department of Homeland Security, little improvements have been made to the preparedness of such hospitals or providers to respond to a chemical terrorist attack. As such, this study makes recommendations on how integrated chemical terrorist attack plans can be implemented, including upgrading of both the clinical skills and well as the infrastructure of hospitals and providers, as well as the designation of regional/citywide chemical receiving facilities.

Islámský štát a chemické zbrane

The article deals with topic of Islamic State and chemical weapons. The issue is analysed in three dimensions: origin of used chemical weapons and possibility of independent production; known chemical attacks and tactical regularities in their execution; and traits of future chemical terrorist attacks. By providing a thorough examination of the problem, the article aims at predicting the future development of the group's chemical program as well as describing any prospective chemical terrorist attacks in Europe.

Chemical Terrorism for the Intensivist

The use of chemical agents for terrorist attacks or military warfare is a major concern at the present time. Chemical agents can cause significant morbidity, are relatively inexpensive, and are easy to store and use. Weaponization of chemical agents is only limited by the physicochemical properties of some agents. Recent incidents involving toxic industrial chemicals and chemical terrorist attacks indicate that critical care services are frequently utilized. For obvious reasons, the critical care literature on chemical terrorism is scarce. This article reviews the clinical aspects of diagnosing and treating victims of chemical terrorism while emphasizing the critical care management. The intensivist needs to be familiar with the chemical agents that could be used in a terrorist attack. The military classification divides agents into lung agents, blood agents, vesicants, and nerve agents. Supportive critical care is the cornerstone of treatment for most casualties, and dramatic recovery can occur in many cases. Specific antidotes are available for some agents, but even without the antidote, aggressive intensive care support can lead to favorable outcome in many cases. Critical care and emergency services can be overwhelmed by a terrorist attack as many exposed but not ill will seek care.

Decontamination and management of human remains following incidents of hazardous chemical release

To provide specific guidance and resources for systematic and orderly decontamination of human remains resulting from a chemical terrorist attack or accidental chemical release. A detailed review and health-based decision criteria protocol is summarized. Protocol basis and logic are derived from analyses of compound-specific toxicological data and chemical/physical characteristics. Guidance is suitable for civilian or military settings where human remains potentially contaminated with hazardous chemicals may be present, such as sites of transportation accidents, terrorist operations, or medical examiner processing points. Guidance is developed from data-characterizing controlled experiments with laboratory animals, fabrics, and materiel. Logic and specific procedures for decontamination and management of remains, protection of mortuary affairs personnel, and decision criteria to determine when remains are sufficiently decontaminated are presented. Established procedures as well as existing materiel and available equipment for decontamination and verification provide reasonable means to mitigate chemical hazards from chemically exposed remains. Unique scenarios such as those involving supralethal concentrations of certain liquid chemical warfare agents may prove difficult to decontaminate but can be resolved in a timely manner by application of the characterized systematic approaches. Decision criteria and protocols to "clear" decontaminated remains for transport and processing are also provided. Once appropriate decontamination and verification have been accomplished, normal procedures for management of remains and release can be followed.

Developing Health-Based Pre-Planning Clearance Goals for Airport Remediation Following a Chemical Terrorist Attack: Decision Criteria for Multipathway Exposure Routes

ABSTRACT In the event of a chemical terrorist attack on a transportation hub, post-event remediation and restoration activities necessary to attain unrestricted facility re-use and re-entry could require hours to multiple days. While timeframes are dependent on numerous variables, a primary controlling factor is the level of pre-planning and decision-making completed prior to chemical release. What follows is the second of a two-part analysis identifying key considerations, critical information and decision criteria to facilitate post-attack and post-decontamination consequence management activities. Decision criteria analysis presented here provides first-time, open-literature documentation of multi-pathway, health-based remediation exposure guidelines for selected toxic industrial compounds, chemical warfare agents, and agent degradation products for pre-planning application in anticipation of a chemical terrorist attack. Guideline values are provided for inhalation and direct ocular vapor exposure routes as well as percutaneous vapor, surface contact, and ingestion. Target populations include various employees as well as transit passengers. This work has been performed as a national case study conducted in partnership with the Los Angeles International Airport and The Bradley International Terminal. All recommended guidelines have been selected for consistency with airport scenario release parameters of a one-time, short-duration, finite airborne release from a single source followed by compound-specific decontamination.

Developing Health-Based Pre-Planning Clearance Goals for Airport Remediation Following Chemical Terrorist Attack: Introduction and Key Assessment Considerations

ABSTRACT In the event of a chemical terrorist attack on a transportation hub, post-event remediation and restoration activities necessary to attain unrestricted facility re-use and re-entry could require hours to multiple days. While restoration timeframes are dependent on numerous variables, a primary controlling factor is the level of pre-planning and decision-making completed prior to chemical terrorist release. What follows is the first of a two-part analysis identifying key considerations, critical information, and decision criteria to facilitate post-attack and post-decontamination consequence management activities. A conceptual site model and human health–based exposure guidelines are developed and reported as an aid to site-specific pre-planning in the current absence of U.S. state or Federal values designated as compound-specific remediation or re-entry concentrations, and to safely expedite facility recovery to full operational status. Chemicals of concern include chemical warfare nerve and vesicant agents and the toxic industrial compounds phosgene, hydrogen cyanide, and cyanogen chloride. This work has been performed as a national case study conducted in partnership with the Los Angeles International Airport and The Bradley International Terminal. All recommended guidelines have been selected for consistency with airport scenario release parameters of a one-time, short-duration, finite airborne release from a single source followed by compound-specific decontamination.

Chemical agent detector placement methodology

Terrorism is a threat to global peace in our world today and in the future this terrorist threat is surely going to be important. Global terrorist groups have highly sophisticated weapon systems with them to terrorize the humanity. Asymmetric warfare which is accepted especially by rough states against free nations is also a threat to humanity. It includes terrorism, weapons of mass destruction, electronic and information war. In this concept, nuclear, biological and chemical (NBC) weapons are the most preferred ones in asymmetric warfare strategy because of their special characteristics. According to this strategy; cities, urban territories, critical military and civilian facilities are the main targets of terrorist attacks. In many developing countries, military zones which were located out of cities at first, happened to be surrounded by urban territories. This situation made the military zones more vulnerable to attacks by terrorists hiding amongst civilians. Another reason for military zones to be a possible target for attacks is the great terror on civilians which will be probably caused by such an attack. In this kind of sensational attacks, chemical agents and chemical weapons will be probably used because of their characteristics. This analytical research is done because key military zones mentioned above must be defensed against these kinds of attacks. While formulating the problem, to find the best locations for the point and the line of sight detectors which are used to identify chemical hazard and warn friendly forces about approaching danger, two models are structured and proposed on the basis of The Maximal Covering and The Maximal Expected Covering Models. In the proposed models, the optimum locations for detectors and alarms are found and the best matching between these detectors and alarms is given. In this research, for a threat point to be covered by a detector, that point must be in the detection range and an alarm must be linked to that detector. Additionally, for the line of the sight detection systems, a threat point must be in the line of sight of detectors. According to the method of this research, chemical defence systems are tried to be optimally set in key military zones during peace time well before attacks. With the proposed models, a solution and an analysis are done in a selected military zone as an example and that zone is tried to be defensed against a possible chemical terrorist attack.
