Ten Afghan security personnel have been killed in fighting with Taliban militants in the western province of Herat.
A local police spokesman says five police officers and five soldiers died in the gun battle on Monday.
He says a district police chief was among those killed in the fighting, which began when the Taliban attacked a police convoy.
Meanwhile, NATO said it may have been responsible for the "unintended but nonetheless tragic" deaths of three Afghan civilians during an operation Sunday in Logar province.
The coalition said insurgents were killed in the raid.
Afghan President Hamid Karzai condemned the NATO operation, saying it resulted in the deaths of four children who were grazing animals at the time.
Civilian casualties have been a source of tension between the Afghan government and U.S.-led NATO forces in the country.
In other news, NATO says a U.S. service member was killed in an insurgent attack in eastern Afghanistan.
