Rashevska is the lead for international justice at the Regional Centre for Human Rights, a non-governmental organisation reporting on human rights abuses in Ukraine. Following the outbreak of the
Russo-Ukrainian war in 2014, she started a project documenting the deportation of Ukrainian soldiers from
Crimea to
Russia. In 2022, following the
Russian invasion of Ukraine, Rashevska initially left Kyiv for
Vienna,
Austria, before returning to Ukraine shortly afterwards. She identified a pattern of children being "evacuated" from occupied areas of Ukraine by Russian authorities, and reported on the subsequent indoctrination,
Russification and militarisation - and, at times, forced adoption - of Ukrainian children in Russia and Russian allies, including
Belarus and
North Korea. Rashevska has criticised the Russian use of the term "evacuation", stating that Russian authorities have not adhered to international humanitarian law concerning evacuation due to not providing lists of evacuated children; completing regular assessments on the justification for ongoing evacuation; and for not working to return children safely to Ukraine. Rashevska instead proposed the term "abduction" be used, and accused Russia of breaching multiple articles of the
Convention on the Rights of the Child. In response to ongoing abductions, Rashevka joined Bring Back Kids UA Task Force, a national expert council. She has called for the development of a universal mechanism for the return of displaced children. Rashevska has addressed the
United Nations Security Council and the
United States Senate on the issue of child abductions. She co-wrote four submissions to the
International Criminal Court, which led to arrest warrants being issued for the
President of Russia,
Vladimir Putin; the Children's Commissioner,
Maria Lvova-Belova; and the
President of Belarus,
Alexander Lukashenko; for the "unlawful deportation" of Ukrainian children into Russia. Rashevska has called on the international community to hold Russian accountable and to enforce the safe return of Ukrainian children; she has criticised countries that have permitted Putin to visit them without honouring the arrest warrant made by the ICC, including
Mongolia and
Tajikistan. == Recognition ==
