SARAJEVO, Bosnia-Herzegovina (AP) — Marking the eve of the centennial of the beginning of World War I in their own way, Bosnian Serbs on Friday unveiled a monument in their part of Sarajevo to the man who ignited the war by assassinating the Austro-Hungarian crown prince on June 28, 1914.

At the other end of the city, the Vienna Philharmonic orchestra was rehearsing for Saturday’s grand EU-sponsored performance, planned as a symbolic start of a new century of peace at the place where the century of wars in Europe started 100 years ago.
