Ukrainian President Volodymyr Zelenskyy on Thursday made an unannounced visit to the International Criminal Court, which has issued an arrest warrant for Russian President Vladimir Putin for alleged war crimes in Ukraine. The visit came a day after Zelenskyy denied that Ukrainian forces were responsible for what the Kremlin called an attempt to assassinate Putin in a drone attack on Moscow. The Kremlin promised retaliation for what it termed a “terrorist” act. On a visit to Helsinki on Wednesday, Zelenskyy told reporters: “We didn’t attack Putin. We leave it to (the) tribunal” — an apparent reference to the ICC. Ukraine’s military claimed three Russian drones that hit the southern city of Odesa early Thursday had “for Moscow” and “for the Kremlin” written on them, seemingly referring to the strikes in Moscow. Also, Kyiv was the target of an air attack for the third time in four days. In total, Ukraine’s Air Forces intercepted 18 out of 24 Iranian-made drones launched by Russian forces in various regions. No casualties were reported. Zelenskyy, meanwhile, was visiting The Hague, which hosts the ICC as well as the United Nations’ top judicial organ, the International Court of Justice. The Dutch city calls itself the international city of peace and justice. Zelenskyy was welcomed outside the ICC building by the court’s president, Poland’s Piotr Hofmanski. Staff crowded at windows to get a glimpse of Zelenskyy’s arrival and raised a Ukrainian flag next to the court’s own flag outside the building. Judges at the ICC last month announced they found “reasonable grounds to believe” that Putin and his commissioner for children’s rights were responsible for the unlawful deportation and transfer of children from occupied areas of Ukraine to Russia. But the chances of Putin standing trial in The Hague are remote. The court does not have a police force to execute its warrants, and the Russian leader is unlikely to travel to any of the ICC’s 123 member states tha
