Islamic State militants have launched a gas attack in a newly-liberated area in western Mosul, the Iraqi military has claimed.
An officer with the anti-terrorism forces said the attack occurred the night before in the al-Abar area, when IS fired a rocked loaded with chlorine.
He said seven soldiers suffered breathing problems and were treated in a nearby field clinic.
US-backed Iraqi forces are currently battling IS militants in the more densely-populated western half of Mosul, with more than half of that area having been retaken.
The extremists were driven out of the eastern half of Mosul, Iraq's second-largest city, in January.
