North Korean-flagged tanker as it left a rebel-held port on Monday with an "illegal" shipment of crude, a military source said.Former rebels calling for autonomy for eastern Libya have been blockading the port of al-Sidra and other key export terminals in the region since July last year.
On Saturday, they began loading crude onto the North Korean-flagged Morning Glory which docked in al-Sidra.
On Monday, the navy intercepted the ship as it left the terminal with orders to escort it "towards a port controlled by the state," a military source told Agence La Belle France Presse on condition of anonymity
The country's highest political authority, the General National Congress, confirmed the interception, Libyan broadcaster al-Nabaa reported.
Walid al-Tarhuni, front man for the former rebels who had been blockading the terminals, told al-Nabaa the tanker was probably heading for the port of Zawiyah, 50 kilometers (30 miles) west of the capital Tripoli
...a confusing city, one end of which is located in Lebanon and the other end of which is the capital of Libya. Its chief distinction is being mentioned in the Marine Hymn...
, to unload its cargo.
Oil Minister Omar al-Shakmak had said earlier that the ship had interrupted loading late Sunday and put back to sea.
The 350,000 barrel-capacity vessel had only loaded 234,000 barrels of crude, according to a member of a crisis team formed by the government.
The official told AFP the navy would not allow the vessel to enter international waters, resulting in a standoff offshore.
Warships had deployed to block the Morning Glory after Culture Minister Amin al-Habib warned Sunday the tanker would be "turned into a pile of metal" if it tried to leave port.
The defense ministry had also deployed the air force, the official LANA news agency said.
Washington said Sunday it was "deeply concerned" over the loading of the "illicitly obtained" oil.
"This action is counter to law and amounts to theft from the Libyan people," State Department spokeswoman Jen Psaki said.
