Libyan insurgents claim to have shot down two warplanes over the oil town of Ras Lanuf and that their pilots' identity cards and accents indicated they were from Syria.

The al-Tabu Front for the Salvation of Libya claims that the Syrian authorities were complicit in the participation of Syrian soldiers.

The insurgents told the relatively reliable Al-Sharq Al-Awsat, as translated by the Lebanese news portal Iloubnan.info, that the government is using mercenary pilots from Syria, Algeria, Ukraine, Serbia and Romania to fly air force warplanes because Libyan pilots are no longer considered reliable.

Muammar Qaddafi’s air force staged new raids on rebels on Tuesday as rebels said they rejected attempt by intermediaries for Qaddafi to talk with the provisional national council.

A council spokesman said there is nothing to talk about until Qaddafi leaves the country. "We're not going to negotiate with him. He knows where the airport is in Tripoli and all he needs to do is leave and stop the bloodshed," the official said, according to Voice of America.
