Halya Coynash: Freed Ukrainian political prisoner says sanctions against Russia must continue to free others

74-year-old Yury Soloshenko, the oldest of the men taken prisoner in Russia during the months after the invasion of Crimea and military conflict in Donbas, is finally back in Ukraine. He and Hennady Afanasyev, who was tried on the same fabricated 'terrorism' charges as Ukrainian filmmaker Oleg Sentsov were exchanged for Yelena Glishinskaya and Vitaly Didenko, who had been in custody for around a year on separatism charges over their role in a Russian-sponsored so-called 'People's Council of Bessarabia'.
