A video footage shows ISIL militants bulldozing and blowing up several Sunni and Shia holy sites in Iraq’s Salahuddin province.

Meanwhile, ISIL terrorists also blew up the historical St. George's church in the city of Mosul.

The terrorist group “has once again turned to bombing churches and mosques after it lost popularity and many of its members to the airstrikes that have targeted strongholds in different areas of the city," said Saad Mamuzin, head of the Kurdistan Democratic Party's (KDP) 14th Branch in Mosul, on Tuesday.

In recent days, the Iraqi army has managed to make numerous gains in the fight against the ISIL militants, pledging to continue the battle against the extremist group.

The Takfiri militants have been carrying out horrific acts of violence, including public decapitations and crucifixions, against all Syrian and Iraqi communities such as Shias, Sunnis, Kurds, Christians and Izadi Kurds.

The West and its regional allies, including Qatar, Saudi Arabia, and Turkey, are giving financial and military support to the militants.
