Cairo: Libya has once again warned companies against buying any crude offered by sepratists who have been in control of three oil ports in the east of the Opec producer for more than five months.
The government has lost control of the ports of Ras Lanuf, Es-Sider and Zuweitina ports, which previously accounted for 600,000 barrels a day of oil exports.
"The National Oil Corp (NOC) warns everybody not to send ships to load or discharge at these (three) ports," the state oil firm said in a statement.
NOC would take legal action against the signing of petroleum purchase agreements with another party, it said.
The status of force majeure has been extended at all three ports, NOC added.
Members of the government have previously warned ships calling without official documentation risk being fired at. [05/01/14]
