Tripoli oil fire near airport raises fears as Libyan factions battle

A fire at the oil depot for the airport in Libya's capital raged out of control Monday after being struck in the crossfire of warring militias battling for control of the airfield, the latest violence to plague the country as foreigners flee the chaos.

Libya's interim government said in a statement that the fire could trigger a "humanitarian and environmental disaster" in Tripoli, appealing for "international help" to extinguish the inferno. It did not say what it specifically needed.

The blaze had spread to a second depot by Monday afternoon, the government said. It was unclear if there were any injuries from the fire.

"The government appeals to all concerned parties to immediately stop firing as the situation has become very grave," the government said.

Libyan television stations called on residents to evacuate areas within a 5-kilometre radius of the airport. Many Libyan families scrambled to leave. Black smoke billowed over the Tripoli skyline.

Mohammed al-Harari, the spokesman for the Libyan National Oil Company, said the oil depot had a capacity of 6 million litres and that if the fire was not brought under control, it could ignite liquid gas nearby.

Fire trucks from several nearby cities and towns have been deployed to help extinguish the blaze, said a Libyan security official, speaking on condition of anonymity because he is not authorized to talk to journalists.

Fire killed 79, wounded more than 400

The battle for control of the airport began two weeks ago when Islamist-led militias mostly from the western city of Misrata launched a surprise assault on the airport, which has been under control of a rival militia from the western mountain town of Zintan. It wasn't clear whose fire started the oil depot blaze.

The Health Ministry said Sunday that the fighting has so far killed 79 people and wounded more than 400.

More than three years after dictator Moammar Gadhafi's downfall, Libya is witnessing one of the worst bouts of violence amid growing lawlessness in the country. Libya's interim government, which relies on militias filled with rebels who battled Gadhafi's forces for security, now finds itself unable to rein them in.

Diplomats urged to flee Libya

The fighting has sparked many to flee the country. On Saturday, the United States evacuated its diplomats from Tripoli to neighbouring Tunisia and shut its embassy. The United Nations Support Mission in Libya and the International Committee of the Red Cross have already withdrawn their staff as well. European nations are warning their citizens to immediately leave the country.

German embassy staff in Tripoli were evacuated on Monday, Foreign Ministry spokeswoman Sawsan Chebli said in Berlin. They will be sent back "as soon as the security situation allows," she said.

Austria also removed its diplomatic staff Monday and urged citizens to leave the country as quickly as possible.

Meanwhile, Egyptian ambassador to Libya Mohammed Abu Bakr, who runs the embassy's affairs from the Foreign Ministry in Cairo, denied on Monday that there were some Egyptian nationals among the 23 people killed when a rocket slammed into a house in Tripoli on Saturday.

Abu Bakr said he was officially informed about this by the Libyan Interior Ministry and did not elaborate.

The Egyptian Foreign Ministry said on Sunday that there were some Egyptian nationals among the 23 killed.
