Tanker exports have been halted at five eastern Libyan ports after forces of warlord Khalifa Haftar shut down the terminals.

Libya's National Oil Company (NOC) said on Sunday that Haftar's Libyan National Army (LNA) and the Petroleum Facilities Guard (PFG) of the central and eastern regions instructed the management of several subsidiaries to halt shipments.

The orders cover Sirte Oil, Harouge Oil Operations, Waha Oil, Zueitina Oil and Arab Gulf Oil Co (AGOCO).
