The only working airport in the Libyan capital, Tripoli, is out of action again, only days after it re-opened.
Rockets were fired in the direction of Mitiga International Airport late on Tuesday.
An armed faction controlling it said there were no casualties or damage, but flights are being diverted to Misrata, nearly 200km (120 miles) east of the capital.
The airport had only reopened on Friday following clashes between rival militias.
A ceasefire, brokered by the United Nations, had been signed by armed groups.
Days of clashes in Tripoli had killed at least 50 people and wounded dozens of others, mainly civilians.
Nearly seven years after the ousting of long-time leader Muammar Gaddafi, who was also killed in the uprising, the North Africa country remains in turmoil.
A UN-backed government is nominally in power in Tripoli but militias occupy much of the rest of the country.
Last week, the BBC’s Clive Myrie reported on the devastating impact the fighting was having on communities. Watch his report:
