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.

The Israeli military says it only targets militants and tries to avoid harming civilians and blames civilian deaths on Hamas because the militants operate in densely populated areas.

At least 31 Palestinians were fatally shot on their way to an aid distribution site in the Gaza Strip on Saturday, while Israeli airstrikes killed at least 28 Palestinians including four children, Palestinian hospital officials and witnesses said.
