Russian activist Vladimir Kara-Murza's lawyer reports his secretive transfer to a Siberian prison in Omsk, raising safety concerns.
The UK Foreign Secretary, David Cameron, called for transparency regarding Kara-Murza's location. Previously unaccounted for, he has now confirmed his move as a disciplinary measure for not following a guard's order.
Despite assurances of his well-being in a letter released by his wife, Evgenia, fears persist due to past assassination attempts on his life.
Kara-Murza was sentenced to 25 years for charges he denies, including spreading misinformation about the Russian military and connection with an "undesirable organization."
His critical stance against Putin's regime and role in securing sanctions against Russian officials for human rights violations are noted. The UK condemned his sentencing, and the US state department labeled it part of Russia's increasing repression.
Kara-Murza, with a dissident family background and British citizenship from his teenage years, faces similar secrecy in prison transfers as Russian opposition leader
Alexei Navalny.
