Serbian ultranationalist Vojislav Seselj has returned to Belgrade after UN war crimes judges ordered his provisional release on health grounds, and on his arrival he vowed to chase the country's leaders from power.
Seselj went to the headquarters of his Serbian Radical Party after his November 12 return and told hundreds of supporters there he would "overthrow [President] Tomislav Nikolic and [Prime Minister] Aleksandar Vucic, our renegades and Serbian traitors."
The Hague-based International Criminal Tribunal for the former Yugoslavia released Seselj to allow him to seek medical treatment in Serbia.
He is prohibited from interfering with victims or witnesses and must return to the tribunal when requested.
Serbian doctors who visited Seselj recently say he is suffering from colon cancer that has spread to his liver.
The 60-year-old Seselj has been in custody in The Hague since 2003 and is awaiting verdicts in his long-running trial.
He is accused of war crimes and crimes against humanity during the wars in the early 1990s that followed the breakup of Yugoslavia.
