The Islamist militia accused of killing the US ambassador to Libya earlier this month has been driven out of its base in the city of Benghazi.

Police and protesters stormed the headquarters of the Ansar al-Sharia group, following huge demonstrations against unofficial militias assuming power in the area.

At least 10 people died during the action, in which the base of another militia - said to have official backing - was also attacked.
