4 January 2012 Last updated at 09:23 GMT

In Libya, four people have been killed and at least five have been injured in a firefight between militias in the centre of Tripoli.

A brigade from the city of Misrata clashed with an armed group from Tripoli over an old intelligence building between Zawiya and Saidi streets.

The skirmishes highlight the continuing security threat posed by disparate militias with significant power in the absence of a national army or police.
