NATO-led troops have accidentally killed three Afghan children in artillery fire in eastern Afghanistan.
Another seven Afghans were wounded in the firing in Paktika province, close to the border with Pakistan, NATO's International Security Assistance Force said.
An ISAF patrol had come under fire in Gayan district and called for artillery to return fire.
The first round accidentally landed too close to a compound and troops called for fire to be halted but a second shell had already been fired.
The force provided medical assistance and evacuated the wounded to military hospitals.
There has been a series of incidents in recent weeks in which Afghan civilians have been killed by international troops in the country to fight Taliban-led insurgents.
Separately, Afghans alleged that international troops had killed four people, including two young boys and their father, in an early morning raid in Kabul.
Hundreds of people demonstrated to protest the killings.
The allegation that foreign forces were involved has not been verified with ISAF.
