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.

The yacht’s passengers included climate activist Greta Thunberg and Rima Hassan, a French member of the European Parliament.

The Israeli military said in a statement that troops had opened fire in southern Gaza but said that it had directed warning shots at a group that was moving towards soldiers and deemed a threat to them.
