A source from the Libyan National Oil Corporation (NOC) said Sunday that it had to decrease production at Sharara and El Feel oilfields after pipelines connecting them with Al-Zawiya port in western Libya were closed.

An armed group loyal to the so-called western operations room of Haftar's forces closed Sunday morning the valves of pipelines connecting the two oilfields to Al-Zawiya port, forcing the workers to decrease production before shutting it down completely until the valves get reopened.

Earlier on Sunday, a tribal group also loyal to Haftar tried to close the two oilfields but local dignitaries intervened as they were worried the step would lead to the shutdown of Ubari power plant.

On Saturday, the NOC declared force majeure on oil exports at central and eastern oil ports after Haftar's forces shut down the ports, which according to NOC will cost Libya losses of 700.000 bpd worth 55 million dollars a day.
