Mali's Ansar Dine Islamists 'split and want talks'

One of the Islamist groups fighting in northern Mali has split and wants dialogue, a statement from the breakaway faction says.

Islamic Movement for Azawad said it was splitting from Ansar Dine, and "rejects all forms of extremism and terrorism".

France sent troops to Mali earlier this month to halt a militant advance.
