France's Fabius says Africa 'must' send troops to Mali

West African leaders have been told they must "pick up the baton" in the military offensive to drive Islamist insurgents out of Mali.

French Foreign Minister Laurent Fabius said France had been obliged to send in troops "very, very rapidly otherwise there would be no more Mali".

Ivory Coast President Alassane Ouattara also called for more support for Mali.
