Former Croatian Serb leader Goran Hadzic has been extradited to The Hague to face war crime charges.
Mr Hadzic, the last remaining fugitive of the International Criminal Tribunal for the former Yugoslavia, faces 14 counts of crimes against humanity and war crimes dating back to the 1991-95 Croatian war.
Serbian security officials arrested Mr Hadzic on Wednesday on a forest road in the Fruska Gora national park region about 65km north of Belgrade.
A source close to the family, who spoke on condition of anonymity, said Mr Hadzic was given permission to visit his mother in Novi Sad as she was too ill to travel to a court in Belgrade where her son has been held since Wednesday.
A Serbian minister has confirmed that he has been extradited.
