A police officer in Somalia says a bomb exploded in the capital, Mogadishu, killing one person and wounding another.

Col. Ahmed Abdi said the blast from a bomb planted in a private luxury car exploded Tuesday in Mogadishu's Hodan district, killing the driver and injuring a nearby pedestrian.

There was no immediate claim for the bombing, the latest in a string of attacks often claimed by the Somalia's Islamic extremist rebels, al-Shabab, who are linked to al-Qaida and are fighting to topple the western-backed government protected by African Union forces.
