Iraqi Kurdish Peshmerga fighters pose for a photo holding an Islamic State (IS) group flag in the village of Sultan Mari west of the city of Kirkuk on March 9, 2015 after they reportedly re-took the area from IS jihadists. IS spearheaded a sweeping offensive in June 2014 that overran large parts of the country north and west of Baghdad, including in Kirkuk province.
