ISIS rounded up and killed 284 people as Iraqi-led coalition forces closed in on Mosul, the terror group's last major stronghold in Iraq, an Iraqi intelligence source said.
Nearly 1,000 people have been treated for breathing problems linked to toxic gases from a sulphur plant that Islamic State militants are suspected to have set on fire near the city of Mosul, hospital sources have said.
The UN has concern for around 1.5 million civilians believed to be trapped inside Mosul.
