Relatives collapsed in grief around sunset at Shifa Hospital, where the four children who had been killed on the rooftop — twin brothers Jihad and Wissam Shuheiber, 8; their cousin Afnan, 10; and a friend, Yassin Al-Himidi, 4 — were laid on a single table in the morgue, their bodies deceptively intact. One of the boys wore only his underpants, decorated with superheroes. The military declined to offer an explanation for the strike on the rooftop. On Wednesday, after an earlier Israeli strike killed four children on the beach, the military said it aimed to kill Hamas militants and called the civilian deaths a “tragic outcome,” but did not provide details of why it hit a simple shack on the beach and fired again as the children fled."
