German Foreign Minister Annalena Baerbock has called for the establishment of a special international tribunal to prosecute Russian leaders over Moscow's invasion of Ukraine.
The Ukrainian government is understandably concerned that Russia cannot be prosecuted for its aggression before the International Criminal Court, she said, as it can deal only with cases in which the plaintiff and the defendant are members of the court, or a case is referred by the UN Security Council.
Russia is not a member of the ICC and, as a veto-wielding permanent member of the Security Council, would probably block any referral.
"We talked about working with Ukraine and our partners on the idea of setting up a special tribunal for crimes of aggression against Ukraine," said Baerbock, adding that such a body could derive its jurisdiction from Ukrainian criminal law.
It could be supplemented with international elements - "at a location outside Ukraine, with financial support from partners and with international prosecutors and judges, so that impartiality and legitimacy are guaranteed", she said.
Ukraine, the EU and the Netherlands have publicly backed the idea of a special tribunal. However, ICC chief prosecutor Karim Khan has warned of the potential for legal fragmentation.
Russia denies accusations of war crimes.
