President of Ukraine Volodymyr Zelensky, who met ICC Prosecutor Karim Khan on his visit to Ukraine, welcomed the arrest warrants for his nemesis in Moscow.
"A historic decision from which historic responsibility will begin," Zelensky said.
Ukraine's Western allies also hailed the move.
US President Joe Biden said the warrant was "justified," and "makes a very strong point," while noting that the United States is not a member of the ICC.
"There is no doubt that Russia is committing war crimes and atrocities in Ukraine, and we have been clear that those responsible must be held accountable," a State Department spokesperson said. "The ICC Prosecutor is an independent actor."
Britain called the decision "welcome" and the European Union said it was "just the start." Human Rights Watch said it was a "big day for the many victims" of Russian forces.
