AbstractThis article offers a first subnational analysis of the relationship between states' dynamic control of Internet access and their use of violent repression. I argue that where governments provide Internet access, surveillance of digital information exchange can provide intelligence that enables the use of more targeted forms of repression, in particular in areas not fully controlled by the regime. Increasing restrictions on Internet accessibility can impede opposition organization, but they limit access to information on precise targets, resulting in an increase in untargeted repression. I present new data on killings in the Syrian conflict that distinguish between targeted and untargeted events, using supervised text classification. I find that higher levels of Internet accessibility are associated with increases in targeted repression, whereas areas with limited access experience more indiscriminate campaigns of violence. The results offer important implications on how governments incorporate the selective access to communication technology into their strategies of coercion.
