Afghan officials say a suicide squad launched an eight-hour assault in the capital on traffic police headquarters Monday, killing three traffic police officers. Authorities say all five attackers were killed in the standoff in Kabul.

Officials say 10 people were wounded in the assault, including four police.

The Taliban has claimed responsibility for the attack.

The assault on the police complex, located near parliament, began early Monday with a huge car bomb explosion.

Officials say three of the assailants were killed in the early part of the attack. Two other insurgents managed to get into the building and fought a gunbattle with Afghan forces.

Authorities say a NATO unit arrived on the scene, but the unit's participation in the operation was reported to have been minimal.

The insurgent attack in Kabul is the second 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.
