there is a “high risk” of ISIS using chemical weapons.
He warned: “As the Islamic State loses ground around Mosul, there is a high risk of the group using chemical weapons to slow down and demoralise advancing enemy forces, and to potentially make an example of and take revenge on civilian dissidents within the city.”
Earlier this week we reported on the shocking image of Iraqi special forces soldiers posing next to the hanging body of an ISIS fighter.
Mosul has been under the control of Isis for two years but Iraqi forces are pushing into the city.
Nearly 1,000 ISIS fighters have been killed in the bloody four week battle to drive them out of their Iraqi HQ.
But the move has come at a cost – with many Iraqi and Peshmerga victims.
Last week Iraqi security forces discovered two mass graves near the city of Mosul containing more than 250 bodies.
The US-backed offensive to crush Islamic State in its last major city stronghold in Iraq has just entered its second month.
ISIS militants have been steadily retreating from areas around Mosul into the city since the battle started on October 17.
An elite army unit, the Counter Terrorism Service, breached the city’s eastern limits for the first time a few weeks ago.
Another breakthrough came when Iranian-backed militias announced the capture of an air base west of Mosul.
The capture of the Tal Afar base also offers the mainly Shi’ite forces a launchpad for operations against ISIS targets inside Syria.
The offensive to take Mosul, the largest city under ISIS control in either Iraq or Syria, is turning into the biggest battle in Iraq's turbulent history since the US-led invasion that toppled Saddam Hussein in 2003.
And those still living in the city are feeling the brunt as they are caught up in the ferocious fighting.
The militants have launched waves of counter-attacks against advancing forces, tying them down in lethal urban combat in narrow streets still full of residents.
