A bomb blast has killed two children who were playing near their village in Afghanistan's eastern Paktika Province.
The governor's office said two other children were seriously injured in the incident, which took place April 29 in the Surobi district near the border with the volatile tribal regions of Pakistan.
One of the injured boys has been taken to a U.S. military hospital in Bagram for treatment.
No one has yet claimed responsibility for the attack, but the governor's office linked the blast to Taliban militants.
