Hundreds if not thousands of armed men are converging on Libya's main oil shipping terminals, which the rival powers in the country's east and west are fighting to control in a battle being watched by global oil markets.
The struggle for the Ras Lanuf refinery and nearby Sidr depot threatens to spiral into an all-out conflict between east and west. Already, it has seen the bloodiest fighting yet between the two camps: around 40 troops from the east were killed over four days as militias backed by western factions stormed the area last Friday, losing a handful of casualties.
Now forces from the east loyal to military strongman Khalifa Hafter are massing nearby, threatening a new assault to wrest back the facilities, which are nominally in the hands of the Tripoli government.
