Libya steps up fight against militias

The Libyan government has deployed newly-equipped and heavily-armed forces in a bid to regain control of the country's security.

For two years, the streets of Benghazi have been controlled by a complicated network of armed militias, many of whom fought to oust Colonel Gaddafi, who now refuse to be controlled by the authorities.

But after a string of attacks, the government is taking action.
