It was the bloodiest conflict Europe had witnessed since World War II. Between 1992 and 1995, almost 100,000 people were killed in the Bosnian War, which erupted after the collapse of Yugoslavia. The bloodshed finally ended when the warring parties agreed to the landmark Dayton peace agreement, on November 21, 1995. Twenty years later, these are some of the haunting images of the conflict and the struggle for peace.
