At least 35 have been killed in roadside bombs and insurgent attacks in Afghanistan in what is being called one of the most violent days in the country for months.
NATO said a bomb killed six of its soldiers in the east, without elaborating.
NATO did not give the nationalities of the soldiers, but AFP quoted a U.S. official as saying all six had been American.
Earlier, an insurgent attack in the south killed one foreign soldier.
Afghan officials said 28 Afghan civilians and police had been killed in southern Kandahar and Helmand provinces.
The violence came as major donors in Tokyo pledged $16 billion in development aid
for Afghanistan over the next four years.
Analysts say there are fears the country could slide back into chaos once most foreign troops withdraw by the end of 2014.
