On Thursday Serbian authorities arrested Ratko Mladić, the wartime commander of the Bosnian Serbs Army. Mladić was arrested in the small village of Lazarevo, near Zrenjanin, a town north of the Serbian capital Belgrade. He was indicted by the International Criminal Tribunal for the former Yugoslavia (ICTY) in 1995 for crimes against humanity, genocide and war crimes. Mladić has to face the charges of being responsible for the siege of Sarajevo and for the genocide in Srebrenica, the largest ethnically-motivated massacre in Europe after World War II.
