Islamic State group has reportedly executed 27 fellow extremists, who had been accused of conspiracy. The execution took place in Iraq’s northern province of Nineveh where ISIS terrorists electrocuted the accused members in a city prison located around 400 kilometers (about 300 miles) north of Baghdad, a Kurdistan Democratic Party spokesman said Monday.

Press TV reported that ISIS had previously executed 112 fellow extremists, including 10 top commanders, in a firing squad in southern Mosul. The suspects allegedly planned to kill Abu Abdul Majid Afar, the self-proclaimed governor of Mosul.

ISIS terrorists earlier released a beheading video apparently showing the execution of a prisoner. ISIS affiliates in the Khurasan province in northeastern Iran reportedly performed the execution. The video starts as a commander welcomes the allegiance of the Islamic Movement of Uzbekistan (IMU) to ISIS, Khaama reported.

It is unclear why the prisoner, wearing an orange jumpsuit, was executed. The exact location of the execution and the identity of the slain prisoner have not been verified either. However, ISIS supporters claim an Afghan security forces member has been beheaded.

The United States recognizes IMU as a terrorist organization, which announced allegiance to ISIS in August. In a video recently released by ISIS, IMU leader Usmon Ghazi as well as other fighters were seen taking oath of allegiance to ISIS and its mastermind Abu Bakr al-Baghdadi.

Another terrorist leader called Sadullah Urgenji also made a video statement in March, claiming that his group was fighting for IMU in northern Afghanistan. The leader said that the militant group recognized the authority of Baghdadi.
