Ukraine said on Monday that the opening of a new international prosecution office in The Hague will hold Moscow's leadership accountable for the war crime of aggression.
Prosecutor General of Ukraine Andriy Kostin said the opening of the centre was a "clear signal that the world is united and unwavering on the path to holding the Russian regime accountable for all its crimes."
The International Centre for the Prosecution of the Crime of Aggression Against Ukraine (ICPA) features prosecutors from Kyiv, the European Union, the United States and the International Criminal Court (ICC).
Kostin added in a statement that the office would fill a "gaping hole in accountability for the crime of aggression", a core war crime of launching a war that the ICC's rules do not allow it to prosecute.
EU Justice Commissioner Didier Reynders said Monday's launch showed Kyiv's allies would "stand with Ukraine for as long as it takes."
"We cannot tolerate the gross violation of the prohibition of the use of force," he told a press conference at the headquarters of the EU judicial office Eurojust, where the ICPA is based.
