Firefighters have put out fires started by an attack by terrorist militants of ISIS at the major Libyan oil terminal of Ras Lanuf, Reuters quoted a spokesman for guards at the terminal as saying on Sunday. At least five of the terminal's 13 tanks were damaged as a result of Thursday's attack, firefighters have said. One of the tanks collapsed completely. Petroleum Facilities Guard spokesman Ali al-Hassi said authorities were still assessing the extent of the damage. The National Oil Corporation (NOC) has said it fears that up to 3 million barrels of oil could be lost and that the terminal, shut since December 2014, faces a lengthy closure.
