Clashes erupted in the Al-Furnaj neighbourhood of Tripoli last night, between the RADA Special Deterrence Forces, and the Tripoli Revolutionaries Brigade.
It was reported that several people were killed, and the clashes resulted in damage to a number of vehicles.
The reason for the clashes was the arrest of a member of the Tripoli Revolutionaries Brigade, led by Ayoub Abu Rass, by RADA forces.
Social media pages circulated video clips in which the sound of gunfire was heard.
Dozens of women found themselves stranded inside a wedding hall near the clashes. Video clips spread on social networking sites showing women crying out from inside wedding halls, on Al-Nawaem Street. They appealed to the fighters to stop the clashes, and open safe corridors to allow them to return home.
The biggest protests for years occurred earlier this month in cities across Libya. This underscored the anger over the lack of elections, and nonexistent public services.
Militias in several cities detained people suspected of involvement, prompting the UN mission to express concern on Thursday.
