During the study, 713 "incidents of destruction," places where buildings and infrastructure had been damaged, were observed and mapped. In areas controlled by the government, only six incidents occurred. The rest of the incidents happened in places under rebel control, contested areas, Kurdish-controlled areas (also contested), or weren't definitively on either side's control or being contested. (You can see the distribution in the map at top.) The distribution lends credence to reports that government forces have been bombarding rebel-controlled areas with long-range weapons like missiles.
