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.

Ten people, including children, were killed in a strike at a water collection point in central Gaza, according to health officials. Israel is investigating the incident.
