The Ukrainian Foreign Ministry accused Russia of "acts of terrorism and discrimination in the course of its unlawful aggression" in the filing to the International Court of Justice, according to the ministry’s statement. The filing itself has no direct consequences, though a finding by the court in Ukraine's favour could be enforceable in some national courts, theoretically triggering legal steps to freeze or seize Russian assets, Reuters said. The Hague-based court had no immediate comment. Kiev is also challenging Moscow's actions on its territory at the International Criminal Court and the European Court of Human Rights, while Ukrainian energy firms Ukrnafta and Stabil have asked the UN's Permanent Court of Arbitration to compensate them for investments lost when Russia seized the Crimean peninsula.
