I find the target a bit strange. Like what's the point? A dormitory for workers in a factory? Why not hit the factory or a warehouse?

At least one of the drones hit when most of the people were already outside. The mayor of the town made a video where he is angry that 2 people were wounded, he could be lying but even if it killed 100s that won't delay shaheed/geran building much, no? Apparently, at least some of the workers there were some highschool students, there is no shortage of those
