Afghan and US-led coalition forces have killed 25 Taleban militants in an operation in the southern province of Helmand, the coalition says.
There has been a lot of fighting in the south of the country
It comes a day after at least 21 people were killed in a car bomb attack and four Canadian troops were killed in neighbouring Kandahar province.
President Hamid Karzai, says the suicide attack was a "cowardly act."
Hundreds of people have been killed in escalating violence in southern Afghanistan in recent months.
A coalition statement said that Afghan and coalition forces were conducting a search operation in the Nahr Surkh district of Helmand when they come under fire from militants.
The security forces retaliated and killed 25 militants, the coalition said.
"The combined force took precise precautions in preventing harm of Afghan civilians during the mission, and no reports indicate injuries to civilians," the statement said.
There has been no independent verification of the fighting.
