BENGHAZI - Suspected Islamic State militants staged an attack on a power and water plant about 80km from the major Sarir oil field in eastern Libya late on Monday, an oil facilities guard said.
Security forces foiled an attempted suicide car bombing by killing the driver, before engaging the attackers in clashes, the guard said. An engineer and a resident also confirmed the attack.
Any threat to the Sarir area would cause particular alarm because more than half of Libya's remaining oil production comes from the region.
No group immediately claimed the attack, but Islamic State fighters have previously targeted against oil installations in Libya, stepping up their campaign against export terminals in the east of the country at the start of this year.
