Cultural icons including Nobel Prize-winning journalist Dmitry Muratov and ballet star Mikhail Baryshnikov have released videos calling on Russian authorities to return the body of opposition leader Alexei Navalny to his family, a week after his death in an Arctic penal colony. Navalny's mother said Thursday that she has seen her son’s body and that she is resisting heavy pressure to agree to a secret burial away from the public eye. Lyudmila Navalnaya said investigators allowed her to see her son’s body in the city morgue.
