Milosevic died of heart failure
Former Yugoslav President Slobodan Milosevic
Rumours have flown since Mr Milosevic's death
Preliminary results from the autopsy conducted on Slobodan Milosevic indicate he died of a heart attack, a Hague tribunal official says.
He was speaking before full results of the autopsy were made public.
The former Yugoslav President was found dead on Saturday in the Netherlands, where he was on trial for war crimes.
Mr Milosevic's lawyer said that the day before he died, he had complained he was being poisoned. Some have also suggested he may have killed himself.
An official at the UN's tribunal at The Hague told journalists that the autopsy results would show Mr Milosevic died of "classical heart failure".
Mr Milosevic, 64, had long suffered from heart problems.
UN chief prosecutor Carla del Ponte has refused to comment on claims that he could have been poisoned or committed suicide.
