A militia opposed to Libya's military strongman Khalifa Haftar on June 14, 2018 attacked eastern oil sites under his control, setting fire to at least one crude reservoir, a military source said. The attack was carried out by the Benghazi Defence Brigades, including fighters driven from Benghazi city by forces loyal to Haftar, the source said.
