A remote-controlled drone attack targeted a fuel depot in Libya's capital Tripoli on Thursday, causing minor damage, the state-owned National Oil Corporation (NOC) said in a statement. The NOC said that technical teams had begun drawing fuel from the tanks to reduce the fuel level as a precaution. There was no immediate claim of responsibility and authorities did not say who they believed was behind the attack. The attack caused minor damage to some pipelines and tanks no. 213 and 220 due to falling shrapnel, said Ahmed Al-Masallati, spokesperson for Brega Petroleum Marketing, which is in charge of Libya's fuel supplies. No casualties were reported and the incident did not impact supply operations. Libyan oil facilities have been subject to repeated attacks and closures for various political and technical reasons since the 2011 uprising that toppled Maammar al-Gaddafi and set off a prolonged period of chaos. In August, fuel storage tanks at the nearby Zawiya oil complex, in western Tripoli, were targeted by several explosive-laden drone strikes that hit one of the tanks and completely burned it. Attempts to target oil facilities represent "a direct threat to the supply system," the NOC said in the statement.
