After the creation of a special tribunal to prosecute the Russian Federation for the crime of aggression, the work of this court will not be long and will take several years.

I think that when the tribunal is launched, it may last several years – no more," Kostin said at a briefing in Kyiv on Thursday, where the United for Justice. United for Heritage international conference is taking place."
