Iraqi rapid response members fire a missile against Islamic State militants during a battle with the militants in Mosul, Iraq, March 11, 2017. Thaier Al-Sudani: "This attack came in the middle of a battle when Iraqi forces were trying to recapture the regional government compound from Islamic State. I was taking pictures of clashes at Mosul's antiquities museum when we spotted an Islamic State drone in the air above us. We dropped to the ground for fear of being attacked by a rocket. I cut my hand and we returned to the car to treat it. When we got there, I saw Iraqi forces firing rockets nearby at an IS target beyond our field of vision, so I resumed taking photographs. I thought this photo was a strong one that expressed the terrible violence of battle. It is another world covering wars compared with news conferences. There is 100 percent danger, and the internet we need to transmit pictures is poor or non-existent." REUTERS/Thaier Al-Sudani/File Photo SEARCH "POY STORY" FOR THIS STORY.
