NAIROBI, Kenya (AP) — A Somali official says a car bomb has killed three people and wounded six others at a checkpoint in the capital.

Salah Omar, a spokesman for the Mogadishu mayor, says the blast occurred Wednesday as soldiers were conducting searches at a checkpoint.

He said the bomb attached to the vehicle was remotely detonated.

The al-Qaida-linked al-Shabab extremist group often targets Somalia's capital.
