A security source said that a military force has launched a large-scale security operation to search for ISIS sleeper cells in Mount Sheikh Ibrahim in the district of Tala'afar in western Mosul.

The operation aims to destroy ISIL strongholds and arrest terrorists hiding in valleys and tunnels.

On Tuesday, the 14th Brigade of Popular Mobilization Forces (PMF) launched a search operation to eliminate ISIS sleeper cells in Nineveh, the aim of the operation was to protect citizens and control the roads through which ISIS terrorists infiltrate into Nineveh.

After the military defeat of ISIS in late 2017, and early 2018, the terrorist group began regrouping the disputed and loosely controlled regions between the Peshmerga forces and Iraqi army. These operations aim to deny the group a safe heaven in these regions.
