Hariga, an oil export port in Tobruk eastern Libya, has been shut down because of a security guard strike, a port official said, Al Arabiya reported Feb. 8. Hariga was the last functioning export port aside from two offshore fields. Before closing, it exported around 120,000 barrels per day. The guards went on strike the morning of Feb. 7, saying they had not been paid. Libya is in middle of a power struggle between two governments , and the effect on the oil industry has led to a budget crisis.
