A Libyan crude oil pipeline was set on fire on April 21 causing losses of between 70,000 barrels per day (b/d) and 100,000 b/d. The pipeline, owned by El-Waha oil company, was feeding the Sidra port from El-Zkout, Reuters reported.

The cause of the fire was unknown, the Libyan National Oil Company (NOC) announced on Twitter. Some Waha sources attributes the attack to a “terrorist group.”

“An explosion and fire broke out as a result of terrorist act in one of the valves on the 24 inch crude oil pipeline northwest of the town of Mrada, some 500 km east of Tripoli,” the Libyan petroleum installation guards said in a statement, according to Xinhua.

“The bombing targeted the same pipeline that was bombed in December 2017, while some maintenance operations were being carried out by the company,” the statement added.

The repairs took over a week to complete, causing estimated losses of more than $10 million.
