Spokesman for the Kurdistan Democratic Party (KDP) in Mosul, Saeed Mamouzini, told Arabic-language al-Sumaria satellite television network on Monday that Daesh terrorists killed their fellow extremists in the city, located some 400 kilometers (248 miles) north of the capital, Baghdad, on the grounds that they had plans to orchestrate a “coup” against the terror group’s leader, Ibrahim al-Samarrai aka Abu Bakr al-Baghdadi.

Mamouzini added that the militants, among them 18 top commanders, were executed by firing squad at a prison in southern Mosul.

The slain terrorists had reportedly planned to kill the self-proclaimed Mosul governor, Abu Abdul Majid Afar, overrun Nineveh Province, break from Daesh and declare war on the terrorists currently positioned in Syria’s northern militant-held city of Raqqa.

The development came on the same day that Daesh extremists rounded up scores of Mosul residents and put them under control to make sure that their relatives, who are currently performing Hajj in neighboring Saudi Arabia, would return to Iraq.

Gruesome violence has plagued the northern and western parts of Iraq ever since ISIL Takfiris launched an offensive in June 2014, and took control of portions of Iraqi territory.

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

Units of army soldiers joined by volunteer fighters are seeking to win back militant-held regions in joint operations, Press TV reported.
