TRIPOLI, Libya — Libya appealed for international help Monday after an oil depot was set on fire during severe fighting between rival militias at Tripoli's international airport in the worst level of violence since the 2011 revolution that ousted Moammar Gadhafi.
The interim government said that fighting between rival militias caused the blaze at the depot, which contains 1.6 million gallons of petroleum and could trigger a "humanitarian and environmental disaster," the government said in a statement.
