DEIR AL-BALAH, Gaza Strip (AP) — The U.N. food agency accused Israel of using tanks, snipers and other weapons to fire on a crowd of Palestinians seeking food aid, in what the territory’s Health Ministry said was one of the deadliest days for aid-seekers in over 21 months of war.

It is one of the highest reported death tolls among repeated recent cases in which people have been killed while looking for aid.

A t least 73 Palestinians were killed on Sunday while trying to get access to food, according to the Hamas-run Gaza Ministry of Health. Another 150 people were injured, Gaza health officials said. The majority of those killed were gathered near the Zikim border between Gaza and Israel.
