Alexei Navalny’s spokesperson has confirmed that the Russian opposition leader died at a remote Arctic penal colony and says he was “murdered.” Kira Yarmysh said on Saturday that an official note handed to Navalny’s mother stated that he died at 2:17 p.m. Friday but that it’s unclear where his body is. Another ally says prison officials told his mother when she arrived at the penal colony Saturday that her son had perished due to “sudden death syndrome.” But Navalny’s team says the late politician’s body was not being returned to his family until official tests were done. Meanwhile, Russian authorities arrested people who came to lay flowers at memorials to victims of Soviet-era purges.
