(Reuters) - Russia has opened a criminal case against a prominent opposition activist on suspicion of spreading false information about Moscow's military campaign in Ukraine, his lawyer said on Friday.

Vladimir Kara-Murza was detained outside his home in Moscow on April 11, hours after CNN aired an interview in which he criticised Russia's actions in Ukraine.
