Investigative reporter friend of Navalny, 'was poisoned' - Breaking news. "Unfortunately, (the most probable hypothesis) is that he was poisoned a second time": Christo Grozev, chief investigative journalist of Bellingcat and friend of the Russian dissident.

"I repeat, this is only circumstantial but at this point everything suggests he was killed on purpose," he said. "The burden of proof that he died alone is now in the hands of the Kremlin because four years ago we proved that they tried to kill him with chemical weapons"
