A fire at Libya’s largest oil port has been extinguished by firefighters, officials said Friday. The blaze at the As Sidra terminal was sparked during a battle between an Islamist militia and forces loyal to the internationally recognized government. The fire briefly pushed global oil prices higher. A top official at the state-owned National Oil Co., who declined to be named, said the fire had been put out at the terminal, but that it was impossible to say when the 400,000 barrels-a-day port could restart loadings. “The fire has burned seven storage tanks and two have collapsed,” he said. The official said Libya’s oil production now stood at 315,000 barrels a day. That is down from 900,000 barrels a day in September, and is a fraction of its normal capacity of about 1.5 million barrels a day.
