GAZA, Nov 18 (SPA) - Israel resealed border crossingswith the Gaza Strip on Tuesday, Reuters reported. Israel had allowed 33 truckloads of supplies into Gaza forthe first time in two weeks on Monday, and Israeli PrimeMinister Ehud Olmert assured Palestinian President Mahmoud Abbashe would not permit a humanitarian crisis to develop there. "The crossings are shut because of ongoing rocket fire,"Peter Lerner, a defence spokesman said, referring to severalbarrages of rockets fired from Gaza on Monday that slammed intoIsraeli towns, causing no injury. International aid groups said the supplies sent in on Mondaywere not enough to alleviate food shortages. Israel has also held up fuel shipments to Gaza's main powerplant, leading to daily periodic electricity blackouts for manyof 1.5 million Palestinians living in the territory. Israel had not allowed UNRWA, a United Nations agency thataids some 750,000 refugees in Gaza, to bring in supplies sinceNov. 4 during cross-border fighting in which more than a dozenPalestinian fighters were killed. --SPA www.spa.gov.sa/608818
