LONDON: A pathologist says the body of former Russian agent Alexander Litvinenko was so radioactive that his post-mortem was “one of the most dangerous” ever undertaken.

Nathaniel Cary said Litvinenko’s body was so hazardous that it was left in place for two days after he died in a London hospital on Nov. 23, 2006, from poisoning with radioactive polonium-210.

Litvinenko, a former KGB agent turned Kremlin critic, fell ill after drinking tea with two Russian men at a London hotel.

Police Det. Insp. Craig Mascall told an inquiry into Litvinenko’s death Wednesday that the men who met Litvinenko, Dmitry Kovtun and Andrei Lugovoi, are still wanted for murder.

In Moscow, Lugovoi told The Associated Press that evidence being presented at the inquiry is “nonsense.” Russia refuses to extradite both suspects.
