Russia and Islam are not Separate: Why Russia backs Al-QaedaArchived 19 December 2007 at the Wayback Machine., by Konstantin Preobrazhensky. According to Preobrazhenskiy, "At that time, Litvinenko was the Head of the Subdivision for Internationally Wanted Terrorists of the First Department of the Operative-Inquiry Directorate of the FSB Anti-Terrorist Department. He was ordered to undertake the delicate mission of securing Al-Zawahiri from unintentional disclosure by the Russian police. Though Al-Zawahiri had been brought to Russia by the FSB using a false passport, it was still possible for the police to learn about his arrival and report to Moscow for verification. Such a process could disclose Al-Zawahiri as an FSB collaborator. In order to prevent this, Litvinenko visited a group of the highly placed police officers to notify them in advance."

In the light of the documentary and other evidence which the parties have submitted to it, the Court, having regard to the standard of proof which it habitually employs when ascertaining whether there is a basis in fact for an allegation of unlawful killing, namely proof “beyond reasonable doubt”, finds it established that the assassination was carried out by Mr Lugovoy and Mr Kovtun.”
Johns Hopkins University and Hoover Institute scholar David Satter described this controversy in the United States House of Representatives: "With Yeltsin and his family facing possible criminal prosecution, however, a plan was put into motion to put in place a successor who would guarantee that Yeltsin and his family would be safe from prosecution and the criminal division of property in the country would not be subject to reexamination. For "Operation Successor" to succeed, however, it was necessary to have a massive provocation. In my view, this provocation was the bombing in September 1999 of the apartment building bombings in Moscow, Buinaksk, and Volgodonsk. In the aftermath of these attacks, which claimed 300 lives, a new war was launched against Chechnya. Putin, the newly appointed prime minister who was put in charge of that war, achieved overnight popularity. Yeltsin resigned early. Putin was elected president and his first act was to guarantee Yeltsin immunity from prosecution." (PDF)Archived 27 September 2011 at the Wayback Machine.
