BRUSSELS, March 12 (Xinhuanet) -- The cause of Slobodan Milosevic's sudden death on Saturday remains unknown after a Dutch forensic team failed to determine it, UN war crimes tribunal president Fausto Pocar said Sunday.

    "Because the Dutch coroners who examined Slobodan Milosevic were unable to establish a cause of death, an autopsy was ordered without delay, as required under Dutch law," the tribunal president said in a statement.

    The body of the former Yugoslav president has been moved to the NFI Dutch medical-legal institute for the autopsy, which was set to begin at 1200 GMT on Sunday.

    "The Registrar has requested that a full report of the Dutch authorities' investigation be forwarded to the Tribunal as quickly as possible," Fausto Pocar said.

    Mirjana Markovic, wife of Milosevic, accused The Hague tribunal of killing her husband. Milosevic's elder brother Borislav said in Moscow that the tribunal must be held responsible for his brother's death.

    The authorities hope the autopsy will put to rest claims that Milosevic was murdered.

    Milosevic, 64, was found dead Saturday in his cell at the UN detention unit in Scheveningen near The Hague. He suffered a heart trouble and high blood pressure that had repeatedly interrupted his trial in The Hague. Enditem
