Mahmoud Abdul Rahman's son, Abdullah, was among six children who died at a water distribution point in Gaza on Sunday.

Israel’s air and ground war has destroyed vast areas of Gaza and driven some 90% of the population from their homes. Aid groups say they have struggled to bring in food and other assistance because of Israeli military restrictions and the breakdown of law and order, and experts have warned of famine.

Israel and Hamas appeared no closer to a breakthrough in indirect talks meant to pause the war and free some Israeli hostages after Prime Minister Benjamin Netanyahu’s Washington visit last week.
