KHANAQUIN, Iraq — The fight against the Islamic State (IS) in northern Diyala province is being conducted against a sand-hued backdrop with a few date trees, slow-moving rivers and rocky outcrops.
Farther north and to the west of the Kurdistan Regional Government (KRG) capital, Erbil, the terrain is flat and featureless, where a few fields and clutches of trees break up the vast, mostly arid expanse around Makhmour.
