The foreign ministers of 25 Western nations have slammed Israel for “drip feeding” aid into the Gaza Strip, as the health ministry in the territory said that more than 1,000 people have been killed seeking humanitarian relief there since late May.

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.

Gaza is facing a severe food crisis, with more than 100 humanitarian aid agencies warning that the population is on the brink of starvation.
