AFP PICTURES OF THE YEAR 2016 A sheperd tends to his blackened flock of sheep as oil wells, set ablaze by retreating Islamic State (IS) jihadists, burn in the background, in the town of Qayyarah, some 70 km south of Mosul on November 20, 2016. Locals told AFP that they face a range of health issues including breathing difficulties, and sheperds said they could not sell their livestock as the sheep's fleece was blackened by smoke. / AFP PHOTO / Odd ANDERSEN
