According to the Islamic state Youtube channel, these two boys are from the town of Nobol and the town of Alzaharaa in Aleppo (these 2 towns are known by their support to the regime). According to Al-Qaeda the children were kidnapped so the regime could release some of their “brothers” but the regime didn’t respond to their demands. So they execute them.
