Bomb attack hits Somali capital

A policeman and 13 civilians have been killed in a suicide bomb attack in the Somali capital, Mogadishu.

The city's governor said the bomb was detonated at a police checkpoint, close to a lookout post belonging to the African Union Peacekeeping Mission.

He said it was not immediately clear who was behind the attack.

AU troops, backing the interim government, are guarding Mogadishu's presidential palace, but most of the city is controlled by Islamist rebels.
