A court of appeals in St. Petersburg on September 9 rejected an appeal filed by physicist Anatoly Maslov against the 14-year prison sentence he was handed in May on a high treason charge. The 77-year-old expert in the field of fluid gas was arrested in 2022 on suspicion of passing classified information to a foreign country. Maslov rejects the charge. At least 12 scientists have been arrested in Russia on treason charges since 2018, mostly for activities considered a normal part of scientific work, such as publishing papers internationally, collaborating with colleagues from other countries, and attending international conferences.
