The oil terminal in Ras Lunf Port was taken over by Libyan leader Muammar Gaddafi’s opponents yesterday morning.
Agence France-Presse reported that rebels overtook the port, which is situated 210km west of Ajdabiya, following a past few days of fighting.
Air strikes carried out by the rebels’ allies were thought to have helped them to gain control.
NATO leaders were due to meet yesterday to discuss how to manage military alliance in the country and whether it should take over all United Nations-mandated operations.
NATO is reportedly discussing whether to put in place a mandate that will attempt to protect all civilians from further attacks, something that has already been followed by a US-led coalition.
