At least 12 Palestinians were killed and several others injured Tuesday in new Israeli strikes in the Gaza Strip, medical sources said. Five people lost their lives when Israeli fighter jets hit a house in al-Zarqa neighborhood, northeast of Gaza City, a medical source said.

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.

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.
