Ten prominent Putin critics who have died in assassinations or mysterious circumstances

For over two decades, President Vladimir Putin has squeezed dissent in Russia. Critics, journalists, and defectors have faced dire consequences after opposing him. From poisonings to shootings, mysterious falls from windows, and even plane crashes, there is a long trail of silenced voices, according to Newsweek.
It is noted that Alexei Navalny, whose death in prison is as yet unexplained, had previously fallen ill on a flight from Siberia to Moscow in 2020 after being poisoned with Novichok, a nerve agent. Alexander Litvinenko, a former Russian spy who defected and was a prominent Putin critic, was murdered with polonium-210 in London in 2016.
Newsweek says that other deaths of opposition figures under Putin's rule also appear to follow a pattern. Boris Nemtsov, shot dead near the Kremlin, and Stanislav Markelov, assassinated in Moscow alongside journalist Anastasia Baburova, are just two examples. Natalia Estemirova, abducted and found dead in Chechnya, and Anna Politkovskaya, an investigative journalist murdered in her Moscow apartment building, also paid the ultimate price following their dissent.
According to the publication, here are 10 prominent Putin critics who have died in assassinations or mysterious circumstances. 1. Alexei Navalny died in prison. The Russian prison service reported that he felt unwell after a walk and lost consciousness. Navalny was known for exposing corruption, investigating Putin's inner circle, and leading anti-Kremlin opposition movements. His death is likely to be seen by fellow opposition members as a political assassination attributable to Putin, but is as yet unexplained.
2. Mikhail Lesin was a former Russian press minister and media executive. He fell out of favor with Putin and faced scrutiny for his wealth. Lesin was found dead in a Washington, D.C. hotel room. The official cause of death was ruled as accidental blunt force injuries, but questions persist about the circumstances. 3. Boris Nemtsov was shot dead on a bridge near the Kremlin. His murder remains unsolved, but many believe it was politically motivated. Nemtsov was a vocal critic of Putin's government, advocating for democracy, human rights, and transparency. He served as a deputy prime minister under President Boris Yeltsin and later became a prominent opposition figure. 4. Boris Berezovsky was a wealthy businessman, oligarch, and former ally of Putin. However, he became a vocal critic and fled to the U.K. Berezovsky was found dead in his home in Berkshire, England. The official cause of death was ruled as suicide, but suspicions remain due to his high-profile opposition activities. 5. Sergei Magnitsky was a lawyer and auditor who exposed a massive tax fraud scheme involving Russian officials. He was arrested, imprisoned, and denied medical treatment. Magnitsky died in custody following severe beatings and medical neglect. His death led to the passing of the Magnitsky Act in the United States, which sanctions Russian officials involved in human rights abuses and corruption. 6. Stanislav Markelov was a human rights lawyer and journalist. He was assassinated in Moscow by a gunman who also killed journalist Anastasia Baburova. Markelov had represented victims of human rights abuses and criticized the Russian government's actions in Chechnya. His death raised concerns about the safety of those opposing the regime.
