Funerals have been held for the 10 Afghan girls who were killed by a suspected landmine as they gathered firewood near their village in the east of the country, a government official told Reuters.
Two other girls remain in hospital in a critical condition, the official added.
The head of NATO's International Security Assistance Force (ISAF) said he is "deeply saddened" by the deaths of 10 Afghan girls who were killed by an explosion.
ISAF said the Governor of the Chaparhar district - where the explosion took place - claimed it was the result of "the accidental triggering of an old landmine".
ISAF Commander Gen. John R. Allen said:
Over three decades of conflict, Afghanistan became one of the most heavily mined countries on earth. The tragic and cruel fact about landmines is that they don't discriminate.
These precious children were innocent victims and I express my sincere sympathy and condolences to the families and friends of those affected.
Police say they are looking at whether the 10 young girls may have died after one of them triggered an unexploded mine as they walked through a field in eastern Afghanistan.
Police spokesman Hazrat Hussian says at least one other mine was found nearby.
Afghan officials say the ten girls were killed by an explosion as they gathered firewood outside Dawlatzai village in Nangarhar province's Chaperhar district.
- Officials say the girls are aged between 9 and 13 and all came from different families
- Two others were seriously injured and are in critical condition in hospital
- Officials are investigating if the blast came from a newly planted bomb or from an unexploded mine
