Afghan police say a suicide bomber has attacked a police station in the southern city of Kandahar, killing at least one police officer.

Kandahar police chief Abdul Raziq says the attacker detonated a bomb-laden car outside the station on Monday, injuring at least four other people, both police and civilians. The blast also badly damaged a nearby civilian compound.

There was no immediate claim or responsibility for the attack, but similar bombings in the past have been blamed on the Taliban.
