At least eight policemen were killed on Thursday during an operation by US-led coalition troops in central Afghanistan, which also left several insurgents dead, officials said.
Separately on Thursday, a NATO soldier was killed and two others were wounded when an explosion stuck their patrol in southern Afghanistan, the alliance said in a statement. The nationalities of the dead and wounded soldiers and the exact location of the blast were not given.
The police officers died in Ghariban village in Gavin province during an operation that included US ground forces and air strikes, said a provincial official, Habeb-ul Rahman. It was unclear whether Afghan troops also took part in the raid.
Two other villagers, including a woman, were killed in the clash, Rahman said.
It was not immediately clear how the officers and civilians were killed.
US-led coalition said it killed "several insurgents" and detained nine others during an operation targeting a Taliban commander associated with suicide bombings in Ghazni.
The two sides exchanged fire and the coalition called in air strikes, it said in a statement.
Afghan police officials in Ghazni, who spoke on condition of anonymity since they were not authorized to speak to the media, said the police appeared to have been killed by air strikes, which also destroyed several houses.
Among the officers killed was the former provincial deputy police chief, Rahman said.
