An Afghan police official says six tribal elders were killed by gunmen Sunday in the western province of Herat.
The provincial police chief says the elders were in a vehicle on their way to a mosque when attackers fired on them. At least one person in the vehicle survived the attack.
Police say two people have been detained in connection with the killings.
Elsewhere, Afghan officials say a suicide bomber wounded at least three civilians in the south Sunday when he set off his explosives near a convoy of foreign troops.
The blast occurred near the town of Gereshk in Helmand province.
Also Sunday, the U.S.-led coalition said a soldier died of wounds suffered during a battle Saturday in Kapisa province.
The NATO-led International Security Assistance Force (ISAF) said six NATO soldiers and three Afghan troops were killed in an ambush Friday. It was the heaviest loss suffered by the force in eastern Afghanistan in recent months.
ISAF said another eight NATO soldiers and 11 Afghan troops were wounded in the fighting in Nuristan province.
The Associated Press news agency quotes a senior U.S. military officer Lt. Col. David Accetta as saying American soldiers are among the dead and wounded.
