The Syrian Observatory for Human Rights (SOHR), in what it claims is a conservative estimate, has reported that in the ten months since the establishment of its so-called “Caliphate,” the Islamic State has executed 2154 people.

The SOHR has documented ISIS executions of 123 people in Syria over the course of the past month, from March 28 to April 28, 2015. Charges used to justify the executions have ranged from blasphemy, to espionage for the Nusayri regime, to sodomy to supporting the YPG.

The Islamic State declared the establishment of its “Caliphate” in Syria on June 28, 2014, and since then the ISIS death count has risen to 2154, SOHR says. The figure would include 1362 civilians, including 9 children and 19 women. It also entails 137 fighters of the Nusra Front, 126 of its own members for “exceeding the limits in religion and spying for foreign countries,” though most of these were reportedly arresting for desertion, and finally 529 officers and soldiers of the regime forces.

The figures released by SOHR Tuesday refer only to those executed by ISIS militants, and do not take into account the other casualties of the ongoing conflict. The Observatory also notes that there are still hundreds of missing and detainees inside ISIS jails, and many others whose whereabouts is unknown, many of whom were likely executed as well.
