premise: The operation comes five days after a high-profile Croatian war crimes suspect, former general Ante Gotovina, was arrested in Spain after four years on the run.
  Gotovina's arrest raised the pressure on authorities in Bosnia's Serb entity and neighbouring Serbia-Montenegro to bring about the arrests of Karadzic and his wartime military chief Ratko Mladic, who were both indicted by The Hague-based UN war crimes tribunal more than 10 years ago.
  The two are wanted on charges including genocide over the 43-month siege of Sarajevo and the Srebrenica massacre of an estimated 8,000 Muslim males, the single worst atrocity in Europe since World War II.
  Both remain at large despite bounties of five million dollars for information leading to their arrest offered by the United States.
  Karadzic is thought to spend his time in either Bosnia or across the border in Montenegro and Mladic is widely believed to be hiding in Serbia.
   What were some events that Karadzic was indicted for?
hypothesis: arrests of Karadzic and his wartime military chief Ratko Mladic
