Rival militias in Libya were battling in the capital, Tripoli, on Wednesday.
Exchanges of both heavy and light weapons could be heard coming from an area near the centre of the city.
An Interior Ministry official says the fighting was between militiamen from the city of Misrata and units from Zintan.
Both groups fought to oust the late Colonel Muammar Gaddafi and maintain a heavy presence in the capital.
It is the first time in weeks that a major gun battle has broken out in the centre of the capital.
The latest clashes took place near the coast, close to the Corinthia Bab al-Africa and Marriott hotels. The BBC reports the fighting has now ceased.
