Standing in a defendant's cage in Moscow's Meshchansky district court on Wednesday, Yashin sought to put on a brave face, laughing, sticking his thumbs up, and stretching, an AFP correspondent said.Yashin was detained while strolling through a park in the Russian capital this summer and faces up to 10 years behind bars for allegedly spreading "false" information about the Russian military.The case against Yashin is based on an April YouTube stream in which he spoke about the "murder of civilians" by the Russian military in the Kyiv suburb of Bucha, calling it a "massacre."Another Moscow councilor, Alexei Gorinov, was this summer sentenced to seven years in prison for denouncing the Ukraine offensive.The 61-year-old had questioned plans for an art competition for children in his constituency while "every day children are dying" in Ukraine."
