Iraqi soldier Saad Khudeir displays his tattoo on his body to cover scars of the burns he suffered from a car bomb, in Baghdad, Iraq. In 2008, Khudeir lost his fiancee and suffered burns on his body when a car bomb went off near his home in Sadr City, a district on the eastern side of the capital. Four years later, he endured burns in nearly 70 percent of his body when a suicide bomber rammed his explosives-laden car into his convoy in the then restive city of Fallujah. (AP Photo/Hadi Mizban)
