Afghan officials say a suicide car bombing followed by other explosions and gunfire has rocked the capital, wounding 10 people, including four police.

Authorities say the early Monday attack in Kabul targeted traffic police headquarters located near parliament.

Police say two of the assailants were killed at the entrance. They say at least two other attackers entered the building and engaged in a fire fight with security forces that lasted more than five hours.

Officials say a NATO unit arrived on the scene, but the unit's participation in the operation was minimal.

The Taliban has claimed responsibility for the attack.

It is the second insurgent attack inside Kabul in less than a week. On Wednesday, six Taliban militants attacked the Afghan intelligence agency in downtown Kabul, killing one guard and wounding dozens. Security forces killed all the attackers.
