KABUL — Taliban insurgents wearing suicide vests attacked the Kabul traffic police headquarters before dawn Monday, police said, and eyewitnesses heard numerous explosions while a gun battle was still raging four hours later.
Police officer Mirza Mohammad said at least one insurgent blew himself up at the entrance to the compound and a number of others wearing suicide vests entered the building. Another police officer said at least three attackers entered the building and two were killed. The officer, who could not be named because he was not authorized to speak to the media, said a gun battle was taking place inside the three-story building.
Explosions could be heard inside the building.
A Taliban spokesman claimed responsibility for the attack in a text message to the Associated Press.
Interior Ministry spokesman Sediq Sediqi said the assault began with a suicide car bombing near the building.
‘‘Still there may be one or two inside the building, but we are not sure,’’ he said, adding that four Afghan police commandos were wounded. Sediqi said there were no civilian casualties in the attack.
The area has been surrounded by Afghan security forces, he said.
A unit of NATO special forces that trains Afghan police was at the scene but not taking part in the operation.
It was the second insurgent attack inside Kabul in less than a week. On Wednesday, six Taliban suicide bombers attacked the gates of the Afghan intelligence agency, killing one guard and wounding dozens. Security forces killed all the attackers.
