Afghan and coalition officials say a suicide car bomber has attacked a convoy of U.S. troops in Kabul, killing six civilians and wounding at least 35 people.

Officials say four U.S. soldiers traveling in the convoy escaped Thursday's attack with minor injuries.

The bomb damaged the coalition's two armored vehicles and several other cars along the road near the Kabul airport.

The Taliban has claimed responsibility for the attack.

In other developments, Pakistan lodged a strong protest against coalition forces in Afghanistan Thursday after a cross-border attack killed two women and two children in Pakistan.

Coalition spokesman Major Chris Belcher confirmed that U.S.-led forces fired precision-guided ammunition into Pakistan Wednesday. He said they aimed at a suspected militant target one and half kilometers inside Pakistan.

Separately, Afghan officials say a roadside bomb killed three Afghan police and wounded four others Thursday in Wardak province, southwest of Kabul.

In the southwestern province of Nimroz, the provincial governor said air strikes by Afghan and international forces have killed 41 Taliban militants in the area this week. The U.S.-led coalition has not confirmed the attack.
