Ukraine's Yushchenko victim of poison - doctors

Austrian doctors treating Ukrainian presidential hopeful Viktor Yushchenko today said he was a victim of dioxin poisoning

Austrian doctors treating Ukrainian presidential hopeful Viktor Yushchenko today said he was a victim of dioxin poisoning. However, it remains unclear if it was the result of a deliberate act.

"There is no doubt," Dr Michael Zimpfer, president of the Rudolfinerhaus clinic where Yushchenko is undergoing treatment, told a news conference."There were high concentrations of dioxin, most likely orally administered."

It was impossible to determine, he said, how the poisoning had taken place. "We weren't there and we will leave that to the legal authorities to decide".
