Today, Sarajevo contains many memorials (both official and improvised) related to the siege in the 1990's, and it is clear from these how fresh the war is in the minds of Sarajevo's citizens. Notice the memorial which ends with the admonition: "Do not forget. Remember and warn!" Srebrenica, referenced in the spray-painted sign above, refers to the July 1995 killing of more than 8,000 Bosniaks in the Bosnian village of Srebrenica by Serb paramilitary forces as part of their campaign of "ethnic cleansing" of the Bosnian Muslim villages. The Srebrenica massacre was seen a major failure by the United Nations, which had declared the village to be part of a "safe zone," protected by 400 Dutch peacekeepers who failed to stop the massacre.
