Israeli strikes in the Gaza Strip killed at least 32 people on Sunday, including six children at a water collection point, while the Palestinian death toll passed 58,000 after 21 months of war, local health officials said.

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.

Local hospitals say Israeli strikes across the Gaza Strip overnight and into Monday killed at least 30 people.
