Wearing a T-shirt emblazoned with the words "Don't shoot", a Syrian teenager clings to the side of a damaged building, awaiting rescue by the Syrian Civil Defence, known as the White Helmets. The boy, identified as Maarouf, had been hanging by his leg on the upper floor of the residential building, which collapsed on him after an air strike on Sunday on the rebel-held Qaterji neighbourhood in the northern city of Aleppo. Maarouf was extracted and his injured right leg was treated at a field hospital. He was lucky. White Helmets rescuers later emerged with a dead baby cradled in a blanket, her face caked in dust.
