Russian opposition leader Alexei Navalny has died in jail

Russian opposition leader Alexei Navalny has died in jail, aged 47, under a "special regime" sentence of 19 years. Navalny was a prominent critic of Vladimir Putin, known for exposing government corruption and election fraud. He survived a 2020 novichok poisoning and was arrested upon returning to Russia in 2021. Putin, seeking a fifth term, faces international scrutiny. Navalny's death is widely viewed as a political assassination.
