Deputy Mayor of Rutbah, Imad Ahmad, told Arabic-language al-Sumaria satellite television network on Saturday that Daesh kidnapped the civilians over their participation in a demonstration days earlier against the terrorists in the town, located about 428 kilometers (265 miles) west of the capital, Baghdad.

Ahmad added that members of al-Kabisat and other tribes staged a rally in Rutbah after Daesh executed a Kabisat tribesman in the center of the town on charges of attacking one of the militants and killing him in the process.

Meanwhile, the spokesman for the Kurdistan Democratic Party (KDP) in Mosul, Saeed Mamouzini, said Daesh has executed nearly two dozen fellow militants in the militant-held city.

Mamouzini said Daesh killed five of its own militants on charges of carrying out an armed attack on the self-proclaimed Mosul governor, Abu Abdul Majid Afar, in Qayyarah district of Nineveh Province last July. There were no reports whether Afar was harmed in the assault or escaped unscathed.

Fifteen other Daesh members were executed on charges of fleeing clashes with the Iraqi army and fighters from the Popular Mobilization Units in al-Khazer district of the province.

A local source, speaking on condition of anonymity, also said militants from Daesh have destroyed a mosque in Nineveh Province.

The source said Daesh terrorists placed improvised explosive devices inside Abu Bakr Mosque in al-Shura district, which lies south of Mosul, and later detonated them, leveling the house of worship to the ground.

Moreover, Daesh has obliterated historical paintings inside Virgin Mary and Chaldean churches in downtown Mosul.

The northern and western parts of Iraq have been plagued by gruesome violence ever since the Takfiri Daesh terrorists mounted an offensive in June 2014.

The militants have been committing vicious crimes against all ethnic and religious communities in Iraq, including Shias, Sunnis, Kurds, Christians and others.
