As many of Gaza's more than 2.3 million people desperately wait for humanitarian assistance and food to reach them, aid trucks are being violently ransacked before getting to their destination, say international organizations.

Nearly a hundred aid trucks were looted in southern Gaza on Saturday in what the UN agency for Palestinian refugees has described as “one of the worst” incidents of its kind.

Fighters from Hamas and other Gaza factions have formed an armed force to prevent gangs pillaging aid convoys in the embattled territory, residents and sources close to the group said, after a big increase in the looting of scarce supplies.

UNRWA, the main U.N. agency aiding Palestinians, said its drivers were forced at gunpoint to unload supplies in what it called one of the worst such incidents of the war.

Leaders of the world’s 20 major economies called for a global pact to combat hunger, more aid to war-torn Gaza and an end to hostilities in the Mideast and Ukraine, issuing a joint declaration that was heavy on generalities but short of details on how to accomplish those goals.

The United Nations Relief and Works Agency and the U.N. World Food Programme say more than 100 trucks of food supplies were looted after entering through areas in Gaza under Israeli control over the weekend.

A convoy of more than 100 UN aid lorries carrying food was violently looted in Gaza on Saturday, the UN agency for Palestinian refugees (Unrwa) says. Ninety-seven lorries were lost and their drivers were forced at gunpoint to unload their aid after passing through the Israeli-controlled Kerem Shalom crossing with southern Gaza,
