A woman mourns among graves in Memorial Center Potocari, near Srebrenica, Bosnia and Herzegovina July 11, 2015. Ceremonies are held in Potocari to mark the 20th anniversary of the Srebrenica massacre. Abandoned by their U.N. protectors toward the end of a 1992-95 war, 8,000 Muslim men and boys were executed by Bosnian Serb forces over five July days, their bodies dumped in pits then dug up months later and scattered in smaller graves in a systematic effort to conceal the crime.
