Libyan rebels controlling three oil export ports said yesterday they were ready to negotiate with the government over ending their six-month blockade if Tripoli abandoned plans for a military offensive.

Libyan officials on Wednesday gave the armed protesters two weeks to clear the ports they have seized, or face a military strike. Pro-government and rebel forces clashed briefly this week in central Sirte city linking western and eastern Libya.

The rebels, who are calling for a greater share in the OPEC nation’s oil wealth, managed last week to load oil on to a tanker, which escaped the Libyan navy. The incident embarrassed the weak central government and prompted Parliament on Tuesday to vote the country’s prime minister out of office.

Abb-Rabbo al-Barassi, the eastern autonomy movement’s self-appointed “prime minister”, told Reuters by phone that talks could only begin if the central government withdrew any troops it had sent to central Libya to confront them.

“This is the condition,” he said.

He also said the tanker that had loaded oil last week at one of the rebel-held ports had reached its destination, though he declined to say where. He said more ships were expected at the seized ports.
