Jailed Russian opposition politician Alexei Navalny on Thursday said he has been transferred to a solitary punishment cell, a development he said was clearly designed to shut him up.
Navalny, the most prominent domestic critic of President Vladimir Putin and a strong opponent of the war in Ukraine, is already serving prison terms totaling 11-1/2 years for fraud, contempt of court and parole violations, all of which he rejects as trumped-up charges.
