Bosnian youth, members of NGO "Izvor", tie white bandanas on passing citizens of Sarajevo, on Thursday, May 31, 2012. The "white bandana day" campaign invites people to put an end to genocide denial by marking 20 years since the day, in the beginning of Bosnia's inter-ethnic war 1992-95, when Bosnian Serb authorities issued an order for non-Muslim population of Western-Bosnian town of Prijedor to clearly mark their houses with white flags and to wear white bandanas in public. This was the second time in modern history that such a method of public segregation was implemented in Europe. The first case was recorded in 1939, in Nazi occupied Poland, when Polish Jews were ordered to be marked in similar fashion. (AP Photo/Amel Emric) less
