Input: Al-Qayyara, Iraq (CNN) Menacing black smoke hangs over the town of al-Qayyara. The air here is poison. Children with blackened hands and soot-stained faces play beneath the toxic plumes.

The dark filth coating the landscape and choking residents' lungs comes from oil wells sabotaged and set alight by ISIS in August. Engineers and firefighters have been battling the flames for 100 days now. When CNN first visited al-Qayyara back in early October, they had tackled six fires with nine to go.
