Israel renewed fuel deliveries to the Gaza Strip on Tuesday, ending a week-long suspension of supplies that led to blackouts in the Hamas-controlled enclave, Reuters reported. But the U.N. Relief and Works Agency (UNRWA) said it would be forced to suspend food distribution to 750,000 Gazans on Thursday night unless Israel opened the Gaza Strip's border crossings to humanitarian supplies. UNRWA spokesman Christopher Gunness said the agency's warehouses were running out of wheat, meat, powdered milk and cooking oil. About half of Gaza's 1.5 million residents lost power on Monday when their sole power plant shut down, due to what Palestinian officials said was a lack of fuel. Israel had blocked shipments of EU-funded fuel for a week .
