Gaza's Health Ministry said on Wednesday that at least one Palestinian was killed and 48 were wounded when gunshots were fired on a crowd that overran a new aid distribution site in the war-battered enclave that was set up by an Israeli and U.

The Israeli military is again advancing into Gaza and has blocked most aid, causing widespread hunger. A new but widely criticized system for getting relief in started operating this week.

After the failed attempt to create a humanitarian pier to deliver aid by sea, skepticism ran high that outside actors could facilitate the mass transfer of aid across Gaza. And in the first 48 hours of its operations, the Gaza Humanitarian Foundation faced a slew of online criticism — largely from activists and other aid groups.

A U.S.-backed group approved by Israel to take over aid distribution in Gaza says it has started operations, despite opposition from the U.N. and most humanitarian groups and the unexpected resignation of its executive director.

People stampeded and shots were fired as a Trump-backed plan to distribute food in Gaza at sites guarded by armed contractors got started.

The dispute over whether there should be a temporary ceasefire to release more hostages — as Israel has called for — or a permanent one — as Hamas wants — has bedeviled talks brokered by the U.S., Egypt and Qatar for more than a year and a half, and there’s no indication it has been resolved.

The Israeli military says it was looking into the reported deaths in Al-Bureij and near the American aid centre in southern Gaza.
