Libyan’s protest against Islamist group Ansar al-Sharia
Hundreds of Libyan protesters have stormed the Benghazi headquarters of Islamist group Ansar al-Sharia in a backlash against last week's attack on the US consulate.
Witnesses say militiamen opened fire as the crowd overran the base, but it is not clear if there are casualties.
Buildings and a car were set alight and fighters evicted following a day of anti-militia protests in the city.
US Ambassador Chris Stevens and three others died in the September 11 attack.
