Civilians always bear the brunt of conflict. That is especially the case in Syria, where hundreds of thousands have been killed over more than five years of war and millions have been displaced. It was as clear as ever Thursday after a reported airstrike hit the rebel-held neighborhood of al-Kalasa in the northern city of Aleppo. Footage posted to the YouTube channel of a well-known Syrian civil defense organization, known as the “White Helmets,” depicted the aftermath: sirens blaring, men shouting and pulling bodies from the rubble.
