The widow of Russian opposition leader Alexei Navalny has released new lab test results that she claims show her husband was poisoned while in a Russian prison. The tests, which were conducted by an independent international team, found traces of a nerve agent similar to those used in a previous attack on Navalny. The findings have reignited international outrage and calls for a full, independent investigation into his death. The report directly challenges the official Russian narrative and puts renewed pressure on the global community to hold the Kremlin accountable.
