Deimos-1 image captured smoke rising from Qayyarah oil field, around 60 km south of Mosul, Iraq, on May 11, 2017.

IS torched the oil wells and sabotaged the town’s oil installations before fleeing the area in August 2016, when Iraqi troops forced them to retreat from this oil-producing region. Several fires were burning and spewing out toxic fumes there until April 2017, when Iraqi authorities announced they had finally extinguished them.

However, a fresh Deimos-1 image captured a new smoke plume rising from the oil field.
