The official death toll in Gaza now stands at just under 40,000, though the true number of casualties is likely far higher with many thousands of the dead unaccounted for. In one of the deadliest attacks of the entire war, Israel on Saturday bombed the al-Tabin school in Gaza City where thousands of Palestinians had sought shelter. Officials in Gaza say over 100 Palestinians were killed in the attack, many of them while they were praying at a mosque inside the school. Many of the dead were dismembered or destroyed beyond recognition, with medics reportedly collecting body parts in plastic bags. CNN has confirmed a U.S.-made GBU-39 small diameter bomb was used in the strike, which resulted in “over 100 pieces of people,” says Palestinian journalist Shrouq Aila in Gaza. “I’m saying 'pieces' because nobody was able to recognize the full body of their beloved ones.”
