FORT CAMPBELL, Ky. (AP) - The Army says a suicide bomb attack that killed six American soldiers in Afghanistan used enough explosives to bring down the building the soldiers were in.

The soldiers were from the 101st Airborne Division based at Fort Campbell, Ky. The division's commander, Maj. Gen. John Campbell, said during a videoconference from Afghanistan that 11 soldiers were wounded in the Sunday attack but many were able to return to duty.

Campbell said the attack vehicle was loaded with an estimated 1,000 pounds of explosives. He said the vehicle got past an Afghan security point near a joint NATO-Afghan outpost and hit a wall near the building where the six soldiers were.

Fort Campbell has lost 104 soldiers this year in Afghanistan, where the division has fielded fighters in some of the country's most violent regions.
