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.

Palestinians are being shot or trampled to death while attempting to access aid hubs in the region, yet no party seems to have plans to address the trend.

Charity and human rights groups said Israel’s blockade and ongoing military offensive are pushing Palestinians in the Gaza Strip toward starvation.
