UK sanctions people leading penal colony where Russian opposition leader Navalny died

Britain has issued sanctions against six people who led the penal colony where Russian opposition leader Alexei Navalny died last week, the U.K. Foreign Office said Wednesday. The six prison officials, who were sanctioned under U.K. human rights regulations, include Vadim Konstantinovich Kalinin, who oversaw the brutal prison camp where the anti-corruption campaigner was kept in solitary confinement. Navalny also suffered from being denied medical treatment and from having to walk in temperatures dropping to minus 32 degrees Celsius, the Foreign Office said in a statement.
