Libya has asked for international help after an oil depot caught fire amid clashes over the country's international airport in Tripoli.
The country's interim government said in a statement posted on its website that the fighting between rival militias caused the blaze, which could trigger a "humanitarian and environmental disaster."
It appealed for "international help" but did not specify what sort of help it wants.
Libyan TV stations called on residents to evacuate areas within a three-mile radius of the airport. Many Libyan families responded to the call and scrambled to leave their homes.
