Libya's National Oil Corporation (NOC) has declared a force majeure on crude oil loadings at Zawiya port after sabotage.
Liftings were halted on Saturday after "an unlawful Sharara pipeline valve closure by an unidentified group between Hamada and the Zawiya port the previous evening."
Production was suspended.
Around 290,000 barrels per day (bpd) have been forced offline, with a value of $19m per day.
