Ukrainian opposition leader Viktor Yushchenko’s mystery illness was caused by poisoning, his Vienna doctors say.
The doctors said extensive tests showed a form of dioxin had been used, leaving Mr Yushchenko’s face disfigured.
They described the poisoning as serious and said that if left untreated it could have killed him.
“There is no doubt about the fact that the disease has been caused by a case of poisoning by dioxin,” Michael Zimpfer, the head doctor of the Rudolfinerhaus clinic where Mr Yushchenko is undergoing treatment, said.
“There were high concentrations of dioxin, most likely orally administered.”
Mr Yushchenko’s blood and tissue registered concentrations of dioxin 1,000 times above normal levels.
There appeared to be little lasting damage to Mr Yushchenko’s internal organs, though experts say it could take more than two years for his skin to return to normal.
Interfax reports that the Ukrainian Prosecutor General’s office has reopened its investigation into the poisoning.
