The Libyan National Oil Corporation (NOC) said Thursday that production at El Feel oil field has been interrupted as a result of an unlawful valve closure on the export pipeline from El Feel field to Mellitah.

The Chairman of the NOC, Mustafa Sanallah said this incident is another criminal attempt to disturb the work of NOC, adding that such acts harm the Libyan economy.

"We call on the local leaders and authorities in the area to identify the offenders. NOC will notify the public prosecutor, and will press for those responsible for this damaging and unlawful act to be held to account". Sanallah said.

On November 27, production at El Feel oilfield was suspended as Khalifa Haftar's warplanes struck the vicinity of the field after Sabha military zone forces controlled the oilfield, and then it withdrew in the wake of Haftar's airstrikes.

Sanallah said at the time: "I remind all parties that Libya’s oil and gas fields are vital sources of revenues for the benefit of all Libyans. They must not be treated as military targets."

He added that any fighting in the vicinity of any of oil facilities forces staffers to cease production in order to ensure the safety of employees, saying when production ceases, all Libyans lose out.
