At least two police officers have been wounded in the Somali capital Mogadishu after a car bomb exploded next to a police department building.
Police said the bomb went off on Friday after they had arrested the driver of a car suspected of carrying explosives.
The United Nations is calling for the protection of thousands of Somalis, who've fled fighting in the east of the country.
