BENGHAZI - An oil official in rebel-controlled east Libya said on Thursday forces loyal to Muammar Gaddafi attacked the Sarir oil field, denying a Libyan government charge that it was hit by a British air strike.Asked about Tripoli's claim that an air strike hit Sarir, Abdeljalil Mayuf, information manager at the Arabian Gulf Oil Company (AGOCO), told Reuters: "No, that's not true. There was no air strike. Gaddafi forces attacked this area."A spokesman for the rebel movement based in Benghazi, Mustafa Gheriani, said: "I think it's silly to think the British would do that. It has Mr. Gaddafi's signature all over it."
