Afghan officials say a suicide bomber has attacked a convoy of international troops in the western province of Herat.
Authorities say at least one soldier and two civilians were wounded in the explosion Friday. They say the bomber attacked U.S. forces assigned to train Afghan police.
Also Friday, the U.S.-led coalition announced its forces killed 11 Taliban militants Thursday in an operation against a suspected bombing network.
The coalition says the leader of the network was among those killed in the raid in Kandahar province. The force says the bomb-making cell was responsible for roadside attacks that killed coalition forces.
The coalition says one woman found inside the raided building was taken to a medical facility for treatment of her wounds.
Reporters have not independently confirmed the coalition's statement.
About 70,000 international troops are in Afghanistan fighting a Taliban insurgency that has raged since the United States pushed the extremist group from power in 2001.
