Vladimir Kara-Murza—a prominent Russian activist and politician who has suffered two suspected poisoning attacks by the Russian government in recent years—was arbitrarily detained April 2022 in Moscow for speaking against the war. The Russian government has taken extreme measures to silence dissent and anti-war voices in recent years. Kara-Murza has been sentenced to 25 years in jail in Russia for charges linked to his criticism of the war in Ukraine.
