Palestinians fear hunger will stalk Gaza again this Ramadan after Israel stopped aid deliveries into the enclave due to a ceasefire standoff. Food prices soared, residents said, and aid officials warned Israel against using aid as a weapon of war.

Qatar, a key negotiator of the ceasefire, accused Israel of violating the deal. The U.N. relief chief said aid access must be allowed under international law.

Israel will stop the entry of all humanitarian aid into Gaza to pressure Palestinian militant group Hamas into accepting a temporary extension of the ceasefire agreement, officials said on Sunday, a day after the initial phase of the truce expired.
