Images, perhaps, convey the sadness of the refugee crisis best. Every day we hear about thousands of people being forced to abandon their homes and flee to other countries — their lives broken by never-ending war. These images from northern Iraq, where coalition forces have been pushing against ISIS for months, really drive that message home. Each of the 33 photos serves as a visual reminder of the horror of war, and they will leave no one unmoved. They are testimonies to a reality that should make us think and act.
