Armed militants stormed a police station in the heart of the Afghan capital Kabul on Saturday, triggering an explosion and ongoing heavy exchange of fire, officials and witnesses said.
The attackers got into the police station in the crowded main central market area, close to the Afghan presidential palace, defence ministry and other official buildings.
An Afghan intelligence source, speaking on condition of anonymity, said that one policeman and one civilian were killed and four police wounded. An AFP reporter at the scene also saw four wounded police.
An interior ministry source said a suicide bomber had detonated explosives strapped to his body and the others were fighting police.
The heavily crowded bazaar where the attack took place closed immediately and security forces cordoned off the area.
The Taliban have carried out similar brazen attacks in the past against Afghan security forces.
