The UN relief agency for Palestinian refugees said it could continue its relief mission in the region after receiving a delivery of fuel on Monday, the agency spokesman said.

On April 29 the UN Works and Relief Agency resumed distributing aid in Gaza after a four-day break caused by fuel shortages, but announced Monday that fuel would run out by the evening. The statement was made several hours after Israel closed two major crossing points with Gaza following rocket attacks fire.

"By joint efforts of Palestinian officials in Ramallah and the association for Gaza petrol station owners, who contacted the Israeli side, we were able to receive enough fuel for 20 days of operation," UNRWA Media adviser and spokesman Adnan Abu Hasna told RIA Novosti.

The agency, which delivers basic goods to over 700,000 residents of the enclave, received a total of 200,000 liters of diesel and 20,000 liters of petrol.

Israel has blockaded Gaza since the hard-line Islamic movement Hamas seized control of Gaza from Mahmoud Abbas' Fatah movement in June 2007.

The fuel and food restrictions, the latest in a series of Israeli embargos, were imposed after Palestinian militants attacked the Nahal Oz oil depot, killing two Israeli workers, on April 9.

Israel said it would not ease the blockade unless Hamas stops rocket attacks on Israeli border towns. It has however resumed fuel supplies to Gaza's only power plant, which generates over 30% of the enclave's electricity.
