Huge oil depot blaze puts Tripoli under threat Firefighters on Monday failed to extinguish a blaze at an oil depot on the outskirts of Tripoli, sparking fears of a huge fireball that could cause carnage over a wide area. The depot, about 10 kilometres (six miles) from the Libyan capital, caught fire on Sunday when it was hit by rockets fired by the combattants, who are jostling for control of the airport. IMAGES
