Srebrenica Refugees More than 2,300 Bosnian Muslims packed into NATO trucks to flee the Serbian encirclement of Srebrenica in the spring of 1995. That July, the Serbian army massacred over 7,000 civilians in the city, and outraged public opinion in western Europe and North America finally led to decisive intervention against Serbia. In 2013 several of the Serbian military leaders believed responsible were still on trial for crimes against humanity at the United Nations International Criminal Tribunal. (AP Photo/Michel Euler)
