BENGHAZI: Suspected Islamic State militants staged an attack on a water plant about 80km (50 miles) from the major Sarir oil field in eastern Libya late on Monday, plant officials and 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.
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 oil installations in Libya, stepping up their campaign against export terminals in the east of the country at the start of this year.
There was no damage to Sarir but a crisis committee was being convened on Tuesday to address the growing threat, said Omran al-Zwai, a spokesman for Arabian Gulf Oil Co (AGOCO), which runs production from the field.
The water plant is part of the Great Man-made River, a system built under Muammar Gaddafi to pipe water from desert wells to coastal communities.
A spokesman for the company that manages the plant, Toufik Shwaihdi, said attackers had used rockets, damaging offices and vehicles, but that the system had not been affected.
An official from the plant said staff based there were evacuated, and this might have a temporary impact on water supplies.
As Libya’s conflict has dragged on, production has fallen to about 360,000 barrels per day, less than a quarter of its level before the fall of Muammar Gaddafi in 2011.
Militants loyal to Islamic State have exploited political chaos and a security vacuum to establish a foothold in the country. They took control of Sirte last year, and have a presence in several other towns and cities.
The group has caused extensive damage to oil infrastructure, but has not taken over facilities and profited from them as it has in Iraq.
Western powers have been searching for ways to stop Islamic State’s expansion in Libya, but have been frustrated by recent delays to the formation of a U.N.-backed unity government.
