In this letter dated December 13, 2002, Alexander Litvinenko writes from London to S. A. Kovalyov, chairman of the independent commission investigating the 1999 apartment bombings. Litvinenko addresses the recent arrests of Yusuf Krymshamkhalov and Adam Dekkushev, arguing that while they admitted to transporting hexogen (RDX) and Achemez Gochiyaev admitted to renting basements, they claim they were 'used blindly' and believed they were targeting military sites. Litvinenko highlights the role of suspected FSB agents 'Abubakar' and 'Abdulgofur' as the true organizers and insists the Ryazan incident was a failed FSB operation rather than a training exercise. He urges the Kovalev commission to demand the declassification of the 'Ryazan case' and warns that the FSB will likely coerce the captured suspects into giving false testimony to implicate Gochiyaev as the mastermind. The document explicitly links the FSB to the bombings and the suppression of the truth regarding the Ryazan events.
