“Libyan crude deliveries are currently insufficient, but all the oil fields are well-protected and under the army's control,” Qweri said in an interview.
The oil-rich North African country has been torn by in-fighting between two rival governments since the UN-backed Western invasion helped overthrow Libyan strongman Muammar Qaddafi. The country is controlled by an internationally recognized government in the east and its Islamist-backed rival in the west.
Oil fields have been one of the key targets for Islamist militants fighting in the country. In March 2015, they seized control of the Bahi and Mabruk oil fields in central Libya.
One of Libya's biggest oil depositories, Sidra, has been subject to a series of attacks over the past two years and was closed for months as pro-government forces fought for its control.
In April, the Libyan government made an agreement with the rebels to unblock four oil terminals. Two of them, Zueitina and Hariga, were later transferred to government forces.
