Afghan authorities say a suicide bomber has struck a convoy of French troops in Kabul, killing a French soldier and wounding several Afghan civilians.
Police say Friday's attack took place in the western outskirts of the capital. Taleban insurgents claimed responsibility.
Also Friday, the US military said US and Afghan forces raided an insurgent hideout in southern Helmand province, killing about 40 Taleban fighters. It said large caches of arms and ammunition were seized during the operation in Garmsir district.
The violence came as Afghans marked the UN International Day of Peace. Major cities held events, including kite-flying for children and marches.
Meanwhile, the NATO mission in Afghanistan admitted there were civilian deaths during a NATO airstrike on Wednesday in Helmand's Girishk district. Afghan officials said at least six civilians were killed. NATO said it called in the strike after British-led forces came under heavy fire from Taleban militants.
Militant attacks have soared in recent months in Afghanistan. More than three-thousand people have been killed this year as Afghan, NATO and US forces battle Taleban fighters.
