Two U.N. human rights experts on Monday called for an international and independent investigation into the nearly fatal poisoning of Russian opposition leader Alexei Navalny, an assassination attempt they blamed on Russia as a "sinister" move to silence a prominent Kremlin critic.
The investigation is needed to determine who should be held responsible for poisoning Navalny with a Soviet-era nerve agent and to send a message that intimidation of government critics will not be tolerated by the international community, according to the two United Nations special rapporteurs, or investigators.
