As lockdowns were imposed across the world in the wake of COVID-19, people in conflict-affected states worried that armed groups might try to capitalize on the pandemic and increase attacks. However, a recent APSR article by Brancati, Birnir, and Idlbi suggests that these restrictions on population mobility to address a public health concern had the unintended beneficial effect of reducing violent attacks. They investigate the impact of COVID-19 lockdowns on attacks by armed groups by focusing on the case of the Islamic State of Iraq and Syria (ISIS), an insurgent group, and find that ISIS attacks decreased because of lockdowns, particularly in areas that were heavily populated and areas where ISIS did not have established bases. The authors propose that lockdowns can reduce attacks by groups like ISIS since they reduce the availability of resources and high-value targets while also making it logistically more difficult to carry out attacks.
