Tensions rise as five European countries have publicly stated that Russian opposition leader Alexei Navalny was poisoned, attributing his death to the Kremlin. This assertion, particularly regarding the substance used and the alleged involvement of Russian state actors, escalates existing international friction surrounding Navalny's demise in an Arctic penal colony. His widow, Yulia Navalnaya, has consistently pointed to President Vladimir Putin, a claim Russian officials have firmly rejected.
Background and Timeline
Alexei Navalny, a prominent critic of official corruption and a leader of large anti-Kremlin protests, died on February 16th in an Arctic prison. His imprisonment followed his return to Russia in 2021, where he was immediately arrested and subsequently served the final three years of his life under a 19-year sentence he maintained was politically motivated. Earlier, in 2020, Navalny was flown to Germany for treatment after an incident, during which his family and supporters believed he had been poisoned.
