An Italian citizen, Mario Scaramella, invited a Russian defector, Alexander Litvinenko, to a London restaurant claiming he had some important information about a recent murder of an American female journalist of jewish origin in Moscow.
In a couple of hours after the dinner, Mr Litvinenko felt very sick and was delivered into a London hospital with extremely dangerous poisoning caused by an unknown toxin. He balanced between life and death for several days.
The London police started an investigation. According to intelligence, Mario Scaramella is a close associate of the FSB deputy chief Kolmogorov and visited the FSB headquarters in Moscow several times.
The Russian terrorist Kolmogorov is responsible for internal FSB investigation against Mr Litvinenko, a former FSB colonel who defected to Britain in 2000 and became a British citizen last month. The FSB charged Mr Litvinenko with treason.
In 2001, Mr Litvinenko published a book in the West documenting the blasts of residential houses in Moscow and some other Russian towns carried out by FSB agents in 1999. The FSB accused then the government of the Chechen Republic of Ickeria in executing these blasts and used them as a pretext to start the Second Russian-Chechen War.
The book by Mr Litvinenko is banned in Russia, the Russian-language service of the Chechen news agency Chechenpress reported.
