It was not immediately clear what caused the explosion in volatile Nangarhar province. It could have been a bomb planted by Taliban insurgents or a landmine left over from decades of conflict.

The girls, between nine and 11 years old, were collecting wood in remote Chaparhar district, near the porous border with Pakistan, which is infested with some of the world's most dangerous militant groups.?
"Unfortunately, 10 little girls were killed and two others wounded but we don't know whether it was planted by the Taliban," said Ahmadzia Abdulzai, provincial government spokesman.
Women and children are often the victims of the war between the Taliban and U.S.-led NATO and Afghan forces, now in its 11th year.
More than ten years after the beginning of the war, Afghanistan faces external pressure to reform as well as ongoing internal conflicts.
