JERUSALEM (AP) — Israel is supporting armed groups of Palestinians in Gaza in what it says is a move to counter Hamas. But officials from the U.N. and aid organizations say the military is allowing them to loot food and other supplies from their trucks.

Prime Minister Benjamin Netanyahu said Israel has "operated clans" in Gaza in a video published on social media Thursday after an opposition leader accused him of arming Palestinian militias in order to bolster opposition to Hamas.

The Gaza Humanitarian Foundation has closed its aid distribution sites for the day, without giving a date on when they would open again.

Dozens of people were killed and injured near an aid site run by the Gaza Humanitarian Foundation, a Trump administration-backed aid group.

The U.S.-run Gaza Humanitarian Foundation said it delivered aid to Gaza despite previously stating on its website that sites would be closed. CBS News correspondent Elizabeth Palmer has updates.

The U.S backed-Gaza Humanitarian Foundation said on Friday that all its aid distribution sites in the enclave were closed and a reopening date would be announced later, urging residents to stay away from these sites "for their safety".
