(FILES) This file photo taken on August 20, 2010 shows alleged Russian arms dealer Viktor Bout as he arrives for a hearing at the Criminal Court in Bangkok, in which Thailand's government later approved his extradition to the United States on terrorism charges. - President Vladimir Putin dismissed accusations that Russia was behind cyberattacks against the United States as "farcical" in an interview with NBC broadcast on June 14, 2021 ahead of his summit with President Joe Biden. The Russian leader also said he was open to a prison swap with the United States -- the fate of prisoners is set to be on the agenda when the two meet in Geneva on Wednesday -- and said that jailed Kremlin critic Alexei Navalny would "not be treated any worse than anybody else." Any negotiations over prisoners would focus on individuals including former US marine Paul Whelan who was jailed for 16 years by Russia for espionage. Whelan has urged Biden to arrange a prisoner exchange and said in a recent interview he was victim of hostage diplomacy. Another US citizen, Trevor Reed, was sentenced to nine years in prison in 2020 on charges of assaulting Russian police officers while drunk.Moscow could be eyeing the return of the notorious Russian arms dealer imprisoned by the United States, Viktor Bout, and a contract pilot and alleged drug trafficker, Konstantin Yaroshenko.
