Litvinenko: The investigation into the death of former spy focuses on the role of Moscow

In London, the public inquiry into the death of Alexander Litvinenko resumed, with new revelations. According to the BBC, the Russian ex-spy had escaped two previous murder attempts. During the next two months, the public inquiry will audition in camera, including members of the secret service around a central question: the role of the Russian state in the murder.

The public inquiry is used to establish the facts without comment convictions.

Alexander Litvinenko, a refugee in the UK, drank tea, November 1, 2006 with Lugovoi, a former FSB agent now MP and Dmitry Kovtun, a businessman, in a London hotel.

The same evening, he began to feel ill and had died three weeks later from poisoning by polonium-210, a highly toxic radioactive substance, becoming the first known of a "radiological assassination" victim.

On his deathbed, Litvinenko accused Putin of ordering his murder.

Citing a source close to the investigation, the Daily Telegraph said Saturday that the US Security Agency (NSA) had intercepted communications between people suspected of involvement in the poisoning of Litvinenko and their leader in Moscow shortly after the death.

Litvinenko's widow has little hope of a change of attitude of Russia because the Kremlin still refuses to extradite the main suspect.
