"Russia's top investigative body said on Monday it had opened a criminal case against the International Criminal Court prosecutor and judges who issued an arrest warrant for President Vladimir Putin on war crimes charges. The state Investigative Committee said there were no grounds for criminal liability on Putin's part, and heads of state enjoyed absolute immunity under a 1973 U.N. convention. The ICC prosecutor's actions showed signs of being crimes under Russian law, the committee said, including knowingly accusing an innocent person of a crime. The prosecutor and judges were also suspected of "preparing an attack on a representative of a foreign state enjoying international protection, in order to complicate international relations". The ICC officials targeted in the Russian investigation are prosecutor Karim Khan and judges Tomoko Akane, Rosario Salvatore Aitala and Sergio Gerardo Ugalde Godinez. "The criminal prosecution is obviously illegal, since there are no grounds for criminal liability," the Russian statement said."
