During the past three years, there have been modest signs of opening in Cuba, a one-party communist state ruled by Fidel Castro and then his brother, Raul, since 1959. However, while economic reforms are leading to noticeable changes, freedom of movement, even the right to choose one's place of residence and employment, are still restricted. In a landmark move, the country instituted term limits for the first time last year on top government officials and eliminated the exit-visa requirement that made travel for Cubans difficult, if not impossible. Eased travel restrictions have allowed citizens, including human rights activists like blogger Yoani Sánchez and The Ladies in White, to travel outside the country. Despite these openings, activists are still regularly targeted by authorities. In July 2012, political dissidents Oswaldo Payá and Harold Cepero were killed under suspicious circumstances when the car they were in, driven by Spanish activist Ángel Carromero, struck a tree. Payá's family members claim the car was deliberately forced off the road. Moreover, despite the release of 75 political prisoners in 2010 and 2011, authorities continues to monitor activists and arrest them when they attempt to carry out their work.
