Libya's recognized government has appointed a second official to head state-run National Oil Corp (NOC), it said on Saturday as it vies with a rival government for control of the vital oil sector, Reuters reported. The OPEC producer has had two governments and parliaments since August when a group called Libya Dawn seized Tripoli after a month-long battle with a rival group, forcing the recognized Prime Minister Abdullah al-Thinni to move to the east. Last month, Thinni appointed al-Mabrook Abu Seif as new NOC chairman. In a second step, he named Mohamed al-Arabi as deputy chairman, according to a decree published on a government website. The rival government in Tripoli has named its own oil minister Mashallah Zwai and kept the NOC chairman Mustafa Sanallah in place. -- SPA 21:31 LOCAL TIME 18:31 GMT تغريد
