Russia opened a criminal case against the prosecutor and several judges on the International Criminal Court in an apparent act of retribution for the court issuing an arrest warrant against President Vladimir Putin.

The Russian Investigative Committee said in a Telegram post on Saturday that British prosecutor Karim Ahmad Khan had brought “a knowingly innocent person to criminal liability, combined with the unlawful accusation of a person of committing a grave or especially grave crime.”

The statement said Khan, together with judges Tomoko Akane, Rosario Salvatore Aitala, and Sergio Gerardo Ugalde Godinez, had “issued unlawful decisions” in arresting President Vladimir Putin and Maria Alekseyevna Lvova-Belova, his presidential commissioner for children’s rights.
