The total length of their prison term makes 61 years by four men. Lyudmyla Denisova, the Ukrainian ombudsman reported that on Telegram.
"Russian prosecutors saw to it that Crimean Tatars are illegally detained for the crime they did not commit. Our citizens received the maximum prison time in the high-security penal colony; 18 years for Lenur Khalilov, 18 for Ruslan Mesutov, 13 for Ruslan Nagayev and 12 for Eldar Kantemirov", Denisova wrote.
