Hundreds treated over toxic fumes ‘set alight by ISIS’

QAYYARA, Iraq: Up to 1,000 people have been treated for breathing problems linked to fumes from a sulphur plant set ablaze during fighting with Islamic State in northern Iraq and US officials say US forces at a nearby airfield are wearing protective masks.

A cloud of white smoke blanketed the area around the Mishraq sulphur plant, near Mosul, mingling with black fumes from oil wells that the militants torched to cover their moves.

Local residents and the US military said Islamic State militants deliberately set the sulphur plant ablaze as they strive to repel an offensive by Iraqi government forces to drive them from Mosul, their last major stronghold in the country.

Up to 1,000 people have been admitted to the nearby Qayyara central hospital with respiratory problems since Friday morning and later released, according to hospital director Abdul Salam Jabbouri.

No deaths have been reported at the hospital.

"We have had every type of person come in with breathing problems and burning eyes - children, adults, policemen, soldiers," said Jabbouri.

"Daesh set the sulphur on fire so nobody can come near them."

The Qayyara West airfield is the main US hub to support Iraqi-led operations to retake Mosul. There are about 5,000 US troops in Iraq but the US military has not disclosed the number of personnel at the airfield.

"The winds have actually shifted south, so, as a precautionary measure, the troops at Qayyara West have donned their personal protective equipment - continuing their operations at this point in time," an official said on Saturday, speaking on condition of anonymity.

A Reuters reporter in Qayyara saw Iraqi soldiers wearing gas masks on top of their heads, ready to pull them downIn an examination room at Qayyara hospital, a baby, suffering from inhalation of sulphur fumes, screamed and coughed on Saturday as his father held an oxygen mask over his face.

Most patients have been given oxygen and told to stay away from areas with high sulphur concentration, according to medical aide Saddam Ahmad, who was wearing a surgical mask to protect him from the fumes.
