"Executions in public spaces have become a common spectacle on Fridays in (ISIL power-base) Raqqa and in ISIS-controlled areas of Aleppo governorate," the independent Commission of Inquiry on the human rights situation in Syria said in a report, AFP reported.
Terrorists from the group now calling itself the ISIL are also pushing residents, including children, to attend public executions by beheading or a shot to the head, it said.
"Bodies of those killed are placed on display for several days, terrorizing the local population."
In a 45-page report on the situation in the war-ravaged country, the panel described beheadings of boys as young as 15, men flogged for things like smoking or accompanying an "improperly dressed" female relative, and women publicly lashed for not following the group's strict dress code.
