At least 112 Palestinians were killed and more than 750 others were injured on Thursday after Israeli troops opened fire on civilians gathered at a convoy of food trucks southwest of Gaza City, Palestinian health officials said. Israel denied it was to blame, saying that many victims were run over by aid trucks in a rush to obtain food. The massacre comes as the UN warns of an “almost inevitable famine” in the besieged Palestinian enclave amid increasing reports of children dying of starvation.
