Litvinenko murder was Kremlin-sponsored terrorism

The British government puts the blame for Alexander Litvinenko's murder on the Russian government. From the Sunday Times:

The senior British official was unequivocal. The murder of the former KGB man Alexander Litvinenko was “undeniably state-sponsored terrorism on Moscow’s part. That is the view at the highest levels of the British government”.

This official had access to the latest police and intelligence findings, and he was reflecting the views of senior Home Office counter-terrorism officials, Scotland Yard detectives and others with close knowledge of the murder investigation. All confirmed last week that they believe the plot to poison Litvinenko in London last year was ordered by the Russian secret service, the FSB.
