Goran Hadzic, the former leader of Croatia's ethnic Serbs, was jailed at the United Nations detention center at The Hague Friday after being extradited from Serbia earlier in the day.

Hadzic disappeared in 2004 when the Hague tribunal in the Netherlands indicted him on 14 counts of war crimes and crimes against humanity during the Balkans conflict in the 1990s.

Chief war crimes prosecutor Serge Brammertz told journalists Friday afternoon that “Hadzic will be called upon to answer for the deaths of hundreds and the displacement of thousands.”

Hadzic, who was the last suspect wanted by the United Nations war crimes tribunal, was arrested Wednesday in the mountainous Fruska Gora region, about 65 kilometers north of Belgrade. He will face a single judge when he makes his preliminary appearance before the tribunal on Monday afternoon.

The 52-year-old Hadzic's wife, sister and son, who had not seen him during the seven years he was on the run, visited him early Thursday in the detention unit of Serbia's Special Court building in Belgrade.

Hadzic was arrested two months after police captured former Bosnian Serb military leader Ratko Mladic, who is on trial for genocide for the 1995 Srebrenica massacre of 8,000 Muslim males.
