Thousands of mourners paid their respects to Russian opposition leader Alexei Navalny in Moscow on Friday, as the Kremlin warned his supporters against holding unsanctioned gatherings.His widow, Yulia Navalnaya, who did not attend the service in Moscow, paid tribute to the Kremlin critic on social media platform X after his funeral, thanking him for “26 years of absolute happiness”.“I don’t know how to live without you but I will try my best to make you, up there, happy for me and proud of me. I don’t know if I’ll manage it or not, but I will try,” she wrote.Before the service, a large crowd gathered outside the church following a battle with authorities over the release of Mr Navalny’s body after his unexplained death in an Arctic penal colony.The mourners, including US Ambassador to Russia Lynne Tracy and other Western diplomats, formed a long queue hours before the service started.
