KIEV, Feb. 25 – Impunity for massive human rights violations is one of Ukraine's main problems, Amnesty International said.

"One of the biggest problems registered by Amnesty International in Ukraine, and this is not new to our state, is the impunity problem for gross violation of human rights," Tetiana Mazur, acting executive director of Amnesty International in Ukraine, told a press conference in Kiev on Wednesday while presenting an annual report of the organization for 2015.
