An Afghan official says at least eight children have been killed in a roadside bomb explosion in northern Faryab province.
Karim Yuresh, spokesman for the provincial police chief, says six other kids were wounded in the blast that took place late Friday afternoon in Shirin Tagab district.
Yuresh says that according to a hospital report, two of the wounded kids are in critical condition. All of the children are between 5 and 12 years of age and were playing when the bomb exploded, he added.
No one immediately claimed responsibility for the attack, but Yuresh blamed Taleban insurgents who usually plant roadside bombs to target Afghan security forces in different part of the province.
