Could an oil dispute prolong Libya's war?
Featuring: Wolfgang Pusztai - Chairman of the Advisory Board, NCUSLR
Oil has played a major role in Libya's years-long war. Most of the oil fields are in the country's east, under the control of the Libyan National Army forces.
This means the UN-recognised Government of National Accord in Tripoli has been cut off from a huge source of income. On Friday, LNA forces allowed a tanker to transport some of the crude for the first time in six months. But they reimposed a blockade a day later.
