Health authorities say Israeli strikes in Gaza killed at least 21 people. More than half of those killed late Tuesday and early Wednesday reportedly were women and children.

More than 1,000 Palestinians have been killed by Israeli forces since May while trying to get food in Gaza, mostly near food sites run by an American contractor, the U.N. human rights office said.

The Al-Shaer family went to bed hungry at their home in Gaza City. An Israeli airstrike killed them in their sleep.
