Shaky calm as Bosnia marks war anniversary SARAJEVO, Bosnia-Herzegovina, April 6 (UPI) -- Bosnian capital Sarajevo marked the 20th anniversary of the Bosnian war with a vast symbolic array of empty red chairs and feeble pronouncements of peaceful coexistence among Bosnian Croats, Muslims and Serbs. The somber ceremony was overshadowed by renewed bickering along the ethnic divides of a deeply fractured community that has failed to present a convincing case for EU membership while neighbors including Croatia line up for tying the knot with Brussels. Organizers lined up 11,541 red chairs along the main street in homage to every man, woman and child killed in the siege of Sarajevo, the longest in 20th-century history. The chairs remained unoccupied throughout the memorial ceremony, called the Sarajevo Red Line. Smaller red chairs commemorated children killed in the conflict. The Bosnian war lasted three years and caused more than 110,000 deaths, made 2.2 million homeless and left the country as ethnically divided, though currently at peace, as it was at the war's outbreak. Despite deep-rooted communal differences and equally long-held mutual tolerance, the war's main trigger was the breakup of former Yugoslavia, which reignited each of the competing community's territorial claim. The war's end became possible only after a U.S.-led NATO intervention and the Dayton Agreement, signed in Ohio, on Dec. 21, 1995. An International Criminal Tribunal for the former Yugoslavia is still picking up the pieces from the conflict, pursuing allegations of war crimes by Serb, Croat and Bosnian Muslim former leaders who are alive. Red Line organizer Haris Pasovic announced, "This city needs to stop for a moment and pay tribute to its killed citizens." Public and private groups staged exhibitions, concerts and performances to mark the day, April 6, 1992, when hostilities started with Serbian separatists shooting into a Bosnian unity rally in central Sarajevo that day. Far from resolving the divisions that sparked the fighting, the Dayton Accord has left the communal divisions starkly delineated and beyond an early resolution. The accord divided the country into two entities, Republika Srpska and the Federation of Bosnia and Herzegovina. The federation covers 51 percent of Bosnia and Herzegovina's total area, while Republika Srpska covers 49 percent. The entities are based largely on the territories held by the two warring sides at the time fighting ended. The complex system means that Bosnia has three rotating presidents and each of the mini-states has its own president. The political structure becomes even more complex down the line for a state of only 3.5 million people. Critics say the bureaucracy eats up a half of Bosnia and Herzegovina's national income. The EU wants the state to become more centralized before it will entertain membership for Bosnia and Herzegovina.
