Libya turmoil: Benghazi hit by air strikes and clashes
Gunfire and air strikes have been reported in Libya's second city, Benghazi, amid an offensive to drive out Islamist militias.
The interim government, recognised internationally, has fled to the city of Tobruk, because of unrest in the capital, Tripoli.
However, militias who control Tripoli and Benghazi have announced the formation of their own government.
Libya has been gripped by a power struggle between the militias who drove out Muammar Gaddafi in 2011.
