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.
