Libya's National Oil Company announced a resumption of exports from the Brega terminal in the east, allowing it to partially lift from Thursday a declaration of force majeure. But the Zueitina, Ras Lanuf, Al-Sedra terminals remained blockaded by striking security guards in a dispute over allegations of corruption in oil sales. TOPSHOTS/AFP PHOTO/MAHMUD TURKIA
