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.
