Lugovoi Says Poison From U.K.

The polonium used to kill Alexander Litvinenko originated in Britain, Andrei Lugovoi, the former Federal Guard Service officer wanted in Britain in the alleged murder, said Thursday, exactly one year after the poisoning took place.

"No polonium was found on the Transaero planes on which we flew to and from London," Lugovoi told reporters. "The first traces appeared in London."

Lugovoi, who vehemently denies the charges, accused British authorities of deliberately ignoring evidence that he said absolves him of any wrongdoing.

"Where is the video footage from the bar where we met with Litvinenko?" Lugovoi asked Thursday.

A former Federal Security Service officer and Kremlin critic who fled to Britain in 2000, Litvinenko died Nov. 23 of radiation poisoning from polonium-210.

He met in a London bar with Lugovoi and his partners Nov. 1, 2006.

Lugovoi said instead that he and business partner Dmitry Kovtun were the victims of a "nuclear terrorist attack" masterminded by Kremlin enemies to discredit Russia.

Russia has denied Britain's extradition request, citing a constitutional ban.

A spokesman for the British Embassy refused to "provide a running commentary," as he put it, on Lugovoi's claims, and instead reiterated London's insistence that the extradition request be approved. He spoke anonymously in accordance with embassy policy.
