Kyiv announced Tuesday the return of 2,000 Ukrainian children brought to Russia and Russian-occupied territories since the full-scale invasion began in February 2022, whereas acknowledging that thousands more remain in Russian custody. The announcement comes as international pressure mounts over the alleged forced transfer of Ukrainian children, a practice the International Criminal Court (ICC) has deemed a war crime.
Ukrainian President Volodymyr Zelenskyy stated the returned children had been brought “from under Russia’s control,” in a social media post. He also emphasized the continued plight of those still held, stating that “thousands of Ukrainian children are still held captive by Russia, becoming victims of its crimes every day.”
The ICC issued arrest warrants in March 2023 for Russian President Vladimir Putin and Maria Lvova-Belova, Russia’s commissioner for children’s rights, accusing them of the war crime of unlawful deportation and transfer of children from occupied areas of Ukraine to the Russian Federation. The warrants allege that these actions constitute a direct violation of the Rome Statute.
Ukraine asserts that Russia is systematically attempting to erase Ukrainian identity among the children, including through indoctrination and the imposition of Russian citizenship. These claims are supported by accounts from Ukrainians who have managed to leave Russian-occupied territories, detailing efforts to alter the children’s cultural and linguistic ties to Ukraine.
Moscow acknowledges taking Ukrainian children under its control, maintaining that the transfers were conducted for the children’s safety, removing them from areas of active conflict. Russian officials have stated a willingness to facilitate the return of children when relatives can be identified and verified.
Efforts to secure the return of the children have involved various international intermediaries, including Gulf states and, more recently, Melania Trump, the wife of former U.S. President Donald Trump. These efforts have resulted in the repatriation of children in small groups throughout the course of the war.
In June 2025, President Zelenskyy and Alain Berset, Secretary General of the Council of Europe, signed an agreement establishing a special tribunal to prosecute senior Russian officials for the crime of aggression against Ukraine. This tribunal, the first of its kind established by the Council of Europe, aims to broaden the scope of accountability for actions related to the conflict, complementing the work of the ICC, which focuses on crimes against humanity. The agreement was signed in Strasbourg, France.
The establishment of the tribunal is intended to address the crime of aggression – specifically, the use of armed force by one state against another – an offense not currently within the ICC’s jurisdiction. Zelenskyy has described the tribunal as crucial for holding Russian leadership accountable for the invasion, which began in February 2022 and has continued for over three years.
While the location of the tribunal has not been finalized, The Hague has been suggested due to its existing legal infrastructure. Russia does not extradite its citizens, raising questions about the practical challenges of bringing Russian officials to trial.
