The jihadist group Islamic State (ISIS) executed 91 people in Syria, including 39 of its own members, from July 29 to Aug. 29 on charges that include sorcery and betrayal.

According to the Syrian Observatory for Human Rights (SOHR), the ISIS killed 32 civilians including two women and a pro-ISIS journalist, 11 rebel fighters and at least nine Syrian government soldiers and allied militiamen. Most of them were beheaded.

Those killed were charged with "sorcery, insulting Allah, sodomy, adultery, banditry, joining and cooperating with the awakening movements, cooperating with crusader coalition, mischief on earth and cooperating with the Nusayri regime forces."

Since its declaration of a caliphate in June 2014 up to Aug. 29 this year, the ISIS killed 3,156 people, among them 1,841 civilians, including 76 children and 95 women, the SOHR said.

The executions were carried out in different ways: by shooting, beheading, stoning, throwing off high places and burning to death.

Theyt took place in Damascus, Rif Dimashq, Deir Ezzor, al- Raqqa, al- Hasakah, Aleppo, Homs and Hama, the SOHR report added.

The ISIS also executed more than 930 Arab Sunni civilians belonging to the al-Shaitat tribe in the eastern countryside of Deir Ezzor; 223 Kurdish citizens, who were either shot or beheaded in the city of Ayn al- Arab and the village of Barkh Botan; and 46 civilians who were either burned to death or beheaded in the village of al- Mab'ojah, which is inhabited by people of Alawi, Ismaeili and Sunni sects in the east of the city of Salamiyyah, the SOHR said.

Moreover, the ISIS executed 236 members of the Kurdish YPG, Jabhat al- Nusra, and other rebel groups.

The ISIS also killed 182 of its own members for "exceeding the limits in religion and spying for foreign countries," SOHR said, adding that most of them were executed after they were arrested while attempting to go back home.

A total of 897 officers and soldiers from the Syrian regime forces were also killed by ISIS.

The SOHR has appealed to the UN Security Council and allied countries to stop the crimes against the Syrian people perpetrated by both the ISIS and the Bashar al- Assad regime.

Temple of Bel razed to the ground

Meanwhile, satellite images released by the United Nations confirmed that the Temple of Bel, which became the centre of religious life in Palmyra, Syria, for 2,000 years, had been destroyed by ISIS, according to CNN.

The UN Training and Research Agency released the images to confirm that the temple was completely destroyed.

The UN agency manager Einar Bjorgo said he could "confirm destruction of the main building of the Temple of Bel as well as a row of columns in its immediate vicinity."
