TRIPOLI, Jan 25 (Reuters) - Libya's Petroleum Facility Guards (PFG) have ended their brief blockade of the ports of Ras Lanuf and Es Sider, allowing oil exports to resume there, al-Waha Oil Co said on Monday.

The PFG, a force made up of local groups around Libya tasked with protecting oil facilities, closed down the ports in what it said was a dispute over pay.

An oil engineer at Ras Lanuf said normal work had resumed. (Reporting by Reuters Libya newsroom, writing by Angus McDowall, editing by Susan Fenton)
