Supporters of former Yugoslav president Slobodan Milosevic are passing by his coffin for a second day amid growing doubts that his widow will travel to Serbia for his funeral Saturday.
The former leader's closed flag-draped coffin is on view at a communist-era museum, the Revolution Museum, in Belgrade.
Meanwhile, Russian Communist Party chief Gennadi Zyuganov told reporters in Belgrade the former president's widow, Mira Markovic, lacks sufficient security guarantees and will not be present for the funeral. A Serbian court had suspended an arrest warrant for her on charges of abuse of power, but authorities said they will still require her to surrender her passport and appear before a judge.
Earlier, the president of the United Nations war crimes tribunal, Judge Fausto Pocar, announced that blood tests on Milosevic confirmed he died of a heart attack with no evidence of poisoning. Many Milosevic supporters had voiced concerns he may have been poisoned.
Milosevic died Saturday in his jail cell near The Hague. He was on trial before the U.N. tribunal for genocide and crimes against humanity stemming from the Balkan wars of the 1990s.
