Apostasy in ISIS land is what they use to kill people they consider undesirable but don’t have a legit reason.

QAMISHLI – Extremists of the Islamic State (ISIS) executed 15 civilians on Thursday in Syria’s eastern Deir ez-Zor Governorate. The victims were accused of violating ISIS regulations.

The ISIS-led Sharia Court accused them of fighting the Caliphate and violating the Sharia law.

“The Sharia Court charged the victims with apostasy and ordered ISIS executioners to behead them in public,” local media activist Dahham al-Ali told ARA News.

The 15 civilians were beheaded in front of hundreds of people in the Sabhiya District of Deir ez-Zor on Thursday evening.

“It was a horrible thing to see. People were terrified and everyone remained silent while these brutal executions were taking place,” an eyewitness told ARA News, speaking on condition of anonymity.

“The group hasn’t even explained what those people have done to deserve this. ISIS just accused them of being apostates and beheaded them,” another witness said.

This comes just a few days after ISIS militants executed dozens of prisoners in a major detention centre in the Iraqi northwestern city of Mosul.

“At least 75 prisoners were executed by ISIS in the Mosul Central Prison,” local media activist Abdullah al-Malla told ARA News on Sunday, citing an ISIS official.

Most of the victims were young Iraqi men who have been recently arrested by ISIS militants in Mosul and other parts of Nineveh province. “The Islamic State’s leadership has charged them with treason,” the informed source reported. The executed civilians included at least 25 media activists.
