A number of ISIS terrorists were injured when the Iraqi warplanes shelled a secret ISIS headquarters in northeastern Diyala governorate, a local source said on Tuesday.
The air raid was launched in coordination with the 20th Brigades of the 5th Division of the Iraqi army.
The source asserted that there are still a number of ISIS headquarters that were not identified yet by the Iraqi forces.
Security forces, backed by International Coalition air raids and logistic support of the US army, have retaken eastern Mosul and most of its western part after eight months of battles. These forces are focusing now on liberating Old City's districts that are still under ISIS control.
It is estimated that there are a few of ISIS terrorists left in the second largest city of Iraq. It is expected that they will desperately defend the last pocket of the city that has been once their main stronghold in Iraq.
