The European Union (EU) proposed the establishment of a special court supported by the United Nations (UN) to bring Russia to justice.
Since the start of the invasion of Ukraine earlier this year, Russian troops have been accused of crimes with killings in the Kyiv suburb of Bucha as well as deadly attacks on public facilities.
They include the March 16 bombing of a theater in Mauripol that may have killed nearly 600 people.
As a result the EU called for the establishment of a court to investigate possible war crimes committed by Russia in Ukraine and to use the Kremlin's frozen assets to rebuild the war-torn country.
European Commission President Ursula von der Leyen expressed the bloc's willingness to work with other allies to gain as much international support as possible for the tribunal.
Investigations into military crimes committed during the war in Ukraine are underway across Europe, and the Hague-based International Criminal Court is also launching an investigation.
However, since Russia does not accept the jurisdiction of the International Criminal Court and the European Commission presented two options to the 27 EU countries to hold the Kremlin accountable.
Among them are special independent international courts based on multilateral agreements or special courts integrated in the national justice system with international judges (hybrid courts).
