An Afghan official says that a suicide bomber has killed three foreign troops in an attack on a joint Afghan-NATO foot patrol.

Mohammad Asim Asim, governor of Parwan province said on Monday an attacker on a motorcycle rammed a group of eight troops as they patrolled a village near Bagram Airfield, 45 kilometers (28 miles) north of Kabul.

The Taliban claimed responsibility in an email sent to The Associated Press. The nationalities of the dead NATO personnel were not immediately clear.

Asim says two NATO personnel and three Afghan policemen on the patrol were wounded in the attack.

NATO confirmed the attack took place, but gave no further details.
