The United States today announced a new set of sanctions against six Russian officials, including the deputy justice minister, over the case of Russian dissident Vladimir Kara-Murza, who is accused of “spreading false information” about the war in Ukraine .

The 41-year-old historian and human rights defender was arrested last April in Moscow after speaking out against the Russian invasion of Ukraine. He faces up to 35 years in prison. Russian authorities are charging him over a speech he gave in Arizona in which he spoke “against the Putin regime and war crimes committed by members of the Russian armed forces,” according to the US Treasury Department.

Sanctions were imposed on Deputy Minister of Justice Oleg Sviridenko, judges and investigators involved in the investigation of the case. “The Kremlin’s efforts to silence critics such as Vladimir Kara-Murza will not be able to hide the truth about the war in Ukraine,” US Secretary of State Anthony Blinken tweeted, calling for the immediate release of professor but also “the other prisoners of conscience”.

As part of the sanctions, assets held by these six individuals in the US will be frozen but they and their close relatives will also be banned from entering the country.

Vladimir Kara-Murza is the vice-president of the non-governmental organization “Open Russia” founded by businessman Mikhail Khodorkovsky.
