A source from the International Criminal Tribunal for the former Yugoslavia (ICTY) was quoted by Reuters as saying that "Mladic has been moved to the regular prison wing but has not yet been in contact with other detainees, who include his former political ally, wartime Bosnian Serb President Radovan Karadzic."
Mladic, charged with genocide and other war crimes, was captured in Serbia on 26 May after being on the run for 16 years.
At his initial appearance before the ICTY, the 69-year-old Mladic said that he was a gravelly ill man.
"His lawyers had tried to prevent his extradition citing his poor health, and following his transfer to The Hague he has been kept in the detention centre hospital for medical checks," Reuters said.
