An explosion which appears to be a car bomb rocked the city of Kandahar on Thursday after attackers stormed the police headquarters and then engaged in a gunfight with the Afghan security forces, local police authorities in the southern province said.
Security officials said the explosion occurred near the entrance gate of the headquarters.
Eyewitnesses said that following the first explosion, three back-to-back explosions were heard and the gunfight is still ongoing.
So far, there is no report about causalities.
Taliban has claimed responsibility for the attack.
