Oleg SENTSOV sits behind glass in a cage at a court room in Rostov-on-Don, Russia, Tuesday, July 21, 2015. A Ukrainian filmmaker who has been in jail for over a year now has pleaded not guilty to charges of conspiracy to commit terrorism. 39-year old Sentsov was arrested in Crimea’s capital in May 2014 after a pro-Ukrainian rally protesting Russians annexation of Crimea in March that year.
