UNITED NATIONS: Libya has asked the United Nations Security Council to blacklist an Indian-flagged ship that is on its way to Malta carrying crude oil shipped by the rival eastern Libya government, Libya's UN envoy said on Tuesday.

Libyan Ambassador Ibrahim Dabbashi told Reuters he had written to the Security Council sanctions committee to complain about the first shipment of oil by the rival authorities, which left the eastern Libyan port of Hariga overnight.

The eastern government has set up its own National Oil Company (NOC) to act in parallel to the Tripoli-based NOC that is recognised internationally as the only legitimate seller of Libyan oil.

“We mainly asked the designation of the ship,” Dabbashi said. “We spoke with members of the Indian Mission and gave them the letter we sent to the sanctions committee.”

India's UN mission did not immediately respond to a request for comment.

In March 2014, the Security Council authorised states to board ships suspected of carrying oil from Libyan rebel-held ports and allowed the Libyan government to request that vessels carrying the oil be blacklisted by the sanctions committee.

A 2011 uprising in Libya toppled leader Muammar Gaddafi, but left the country in chaos.

Two competing governments — one in Tripoli and one in the east — backed by militias scrambled for control of the oil-producing country, creating a power vacuum that allowed Islamic State militants to gain a foothold in the North African state.

Leaders of a UN — backed Libya unity government, designed to replace the rival administrations, arrived in Tripoli last month. That government said on Monday it had taken administrative control of seven ministries in Tripoli.
