Serbia's interior minister says officials found copies of Bosnian Serb government documents in the Belgrade apartment where former Bosnian Serb leader Radovan Karadzic lived prior to his arrest last week.

Ivica Dacic said the documents included materials on Bosnian Serb military staff meetings during the conflict in Bosnia-Herzegovina in the 1990s. He said officials turned the materials over to Serbia's war crimes court.

Meanwhile, court officials say the court has not yet received Karadzic's appeal against a judicial order authorizing his extradition to the United Nations war crimes tribunal in The Hague.

Karadzic's lawyer, Svetozar Vujacic says he mailed out the appeal documents shortly before post offices closed Friday. The lawyer confirmed that he does not want the extradition to take place before a planned rally of Karadzic supporters Tuesday.

Prior to his arrest, Karadzic had lived openly, practicing alternative medicine under the name Dragan Dabic.

Officials say they tracked him down by following people thought to be helping him avoid capture.

The Hague tribunal has charged Karadzic with genocide and crimes against humanity for his efforts to ethnically-cleanse Bosnia of Muslims and Croats during the Balkan conflict of the 1990s.

With the Karadzic arrest, the Balkan war crimes tribunal's top fugitive targets now are former Bosnian Serb military chief Ratko Mladic, and ex-Croatian Serb leader Goran Hadzic. Former Bosnian Serb police commander Stojan Zupljanin was arrested last month in Serbia.
