An early March decision by National Oil Corporation (NOC) to lift force majeure at the Es-Sharara oil field in south-west Libya is just one consequence of recent decisive military developments in the southern province of Fezzan. An illegal three-month blockade was lifted when the field was taken over by forces under the command of Field Marshal Khalifa Haftar, commander of the Libyan National Army (LNA) and opponent of the internationally backed Government of National Accord (GNA) in Tripoli.
