ISIS has carried out a chemical attack in a recently-liberated area in west Mosul, injuring several Iraqi troops.

An Iraqi military officer on Saturday reported that missiles loaded with chlorine were fired at al-Abar neighborhood.

The officer spoke on condition of anonymity as he was not authorized to release information.

The attack severely injured at least seven soldiers who face respiratory problems.

Iraqi forces retook control of eastern Mosul back in January after 100 days of fighting, and launched the operation to retake western Mosul on February 19.

Meanwhile, the war-torn country’s federal police announced that they had killed a top ISIS commander and gained control of a network of tunnels used by the terrorist group.

“The forces killed Daesh (ISIS) leader called Mahmoud Ali Mahmoud Matar al-Hadidi during clashes with the group members in the Old City,” said lieutenant General Shaker Jawdat.

“The troops controlled the group’s network of tunnels, in the south of the city, that is used as an alternative headquarters by the leaders,” he added.

According to reports, ISIS has been telling the citizens of the region that the Iraqi forces will kill or imprison them. When the terrorist group failed to deter people from fleeing, it turned to mass executions of people.
