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.

Twenty-one months into Israel’s war in Gaza, the enclave is gripped by escalating scenes of death and hunger, with some killed while trying to reach aid, others dying of starvation and growing condemnation of Israel’s conduct even among many of its closest allies.
