KABUL (AFP) - Seventeen Taliban militants have been killed in clashes with US-led coalition and local forces in Afghanistan in recent days, military officials said Friday. Afghan and US-led troops killed three armed militants and arrested another two during a search operation Friday in western Herat province, Gen Basir Khan, commander of the local army corps, told AFP. Afghan security forces and US-led troops also repelled an insurgent attack Thursday in restive Helmand province, killing four militants, a US military statement said. That incident came a day after Afghan and US-led troops killed ten militants in the same district. Coalition forces also said they had detained four suspected militants in an operation in Kapisa province, north of the Afghan capital Kabul.
