We owe it to the people of Ukraine to bring Vladimir Putin to trial for war crimes | Gordon Brown

The special tribunals for Rwanda and the former Yugoslavia show they work. The US must back one for Russia

It is time to bring Vladimir Putin and his enablers to justice - and the US should now take a lead from Europe. Having witnessed first-hand the devastation inflicted on Ukraine, Joe Biden should mark 24 February, the first anniversary of Russia's invasion, by announcing American support for a special tribunal to try Putin and his henchmen for the crime of aggression.

Biden should make it abundantly clear that there will be no hiding place for those whose invasion has displaced more than 8 million Ukrainians within their own country, and forced nearly 9 million more into exile as refugees. And that there will be no safe haven anywhere in the civilised world for those who are hellbent on inflicting incalculable numbers of injuries and deaths on innocent civilians.
