Mali car bomb 'targets Tuareg checkpoint' in Kidal

A car bomb has exploded in the northern Mali town of Kidal, killing seven people, reports say.

The attack is thought to have targeted a checkpoint manned by a Tuareg group which has come out in support of France's military intervention.

Islamist militants were driven out of Kidal and other strongholds but have continued to stage raids and bombings.

A senior UN humanitarian official has said hundreds of thousands of displaced Malians are too afraid to return home.
