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 acknowledged only that Israel had been working with “clans.” But the opposition leader warned that the “weapons going into Gaza will eventually be pointed at Israeli soldiers and civilians.

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

The Israeli military carried out strikes on Hezbollah “drone factories” in southern Lebanon and suburbs of Beirut on Thursday, as large plumes of smoke could be seen rising from the Lebanese capital.

The Israel Defense Forces said it targeted drone production sites that the militant group had set up in Beirut’s Dahiyeh area and the southern village of Ain Qana, saying Hizbollah was “operating to increase production of UAV’s for the next war”.
