Imprisoned Russian opposition leader Aleksei Navalny has been placed in a punitive solitary confinement cell for the 15th time since August last year, his Telegram channel said on May 11. Navalny was sent to solitary confinement "as a person who is not capable of following correctional guidance," one day after he finished his previous stint in punitive confinement. Navalny's Telegram channel said after serving his new solitary confinement punishment, the Kremlin critic, who has called all of his placements in punitive confinement "politically motivated," will have served 165 days in isolation.
