The Moscow City Court on September 3 sentenced aerodynamics expert Aleksandr Shiplyuk of the Institute of Theoretical and Applied Mechanics in Siberia to 15 years in prison on a treason charge. Investigators say Shiplyuk passed classified information to intelligence operatives from an unspecified country. Earlier reports said Shiplyuk was suspected of passing classified materials to China. The scholar has rejected the charge. Over the last six years, at least 12 employees of the Siberian branch of the Russian Academy of Sciences have been targeted in criminal investigations. Some of them died while in custody. To read the original story by RFE/RL's Russian Service, click here.
