A 23-year-old university student in Siberia has been sentenced to three years in prison for posting a video on the Internet condemning Russia's unprovoked invasion of Ukraine. A court in the city of Tyumen pronounced Kirill Martyushev's sentence on January 30 after finding him guilty of extremism. Martyushev was arrested in March. The court ruled that each day served by the defendant in pretrial detention equals 1 1/2 days in prison and therefore his final prison term will be 18 months.
