Libya’s National Oil Corp said a major oil pipeline was hit by an explosion.
The incident happened in the south of the Libyan terminal of Ras Lanuf overnight between Wednesday and Thursday.
A spokesman for the NOC said it was not clear what had caused the explosion at the people, which has been closed for more than two years.
Last week Ras Lanuf and the nearby terminal of Es Sider came under attack from Islamic State militants.
