Shafaq News/ On Monday, a joint security force arrested a terrorist who killed a policeman before the liberation operations in Dujail district, south of Saladin governorate.

The Iraqi Security Media Cell announced that a joint intelligence force from the Samarra and Dujail Operations Commands and the Commandos Regiment ambushed an ISISA MEMBER in the Albu Hamid area of Dujail and arrested him for killing a police officer in Qara Gul before the liberation operations.

In 2017, Iraq declared final victory over ISIS after Iraqi forces drove its last remnants from the country; the militant group captured about a third of Iraq's territory.

The war has had a devastating impact on the areas previously controlled by the militants. About 3.2 million people remain displaced.

Yet, ISIS still has sleeper cells in several Iraqi Governorates.

The rivalry between Baghdad and Erbil opened up a long, disputed zone among four governorates, Nineveh, Kirkuk, Saladin, and Diyala.

Neither side's forces did not enter this area, which paved the way for ISIS to creep back through these cracks.
