Armed faction enters major Libyan oil ports, putting output at risk

By Ayman al-WarfalliBENGHAZI, Libya (Reuters) - An armed faction entered two major Libyan oil ports on Friday, pushing back forces that captured and reopened the terminals in September, officials and residents said.The move risks increasing the fighting around the ports and casts new doubt over Libya's attempt to revive its oil production.The terminals at Es Sider and Ras Lanuf are two of Libya's largest, with potential combined production capacity of about 600,000 barrels per day (bpd).
