At least ten civilians, including children, were killed when three separate car bombs simultaneously exploded in eastern coastal city of Derna late on Friday, said a Libyan official.
Hamid Albandag, the city’s representative to the General National Council (GNC), said that Friday evening bombings rushed up clashes between local militants affiliated with ISIS and Al Qaeda-linked militants.
The clashes continued into Saturday afternoon.
Derna has been surrounded from all directions by the Libyan army as it restrains from fighting the al Qaida-affiliated militias.
The port city has been a scene of fighting between ISIS militants, rival fighters and armed forces of GNC since last year.
Last month, the Al Qaeda-affiliated militias pushed ISIS militants out of the center of the city, which they had controlled since late 2014.
ISIS lost ground in Derna and now fights on different fronts.
However, it expands along the central northern coastline of the country.
Libya is currently divided between two parliaments, the General National Council (GNC) in the capital of Tripoli, which was founded with the help of the United States and France after the overthrow of Libyan authoritarian leader Muammar Gaddafi in 2011, and the rival House of Representatives (HoR) based in Tobruk.
