A Somali police officer says an explosives-laden vehicle has detonated outside a restaurant in Somalia's capital, Mogadishu.

Capt. Mohamed Hussein says the blast occurred as the restaurant in Waberi district was crowded with diners.

There is no immediate word of casualties.

The al-Qaida-linked al-Shabab extremist group often targets high-profile areas in Mogadishu with suicide bombings.
