Warsaw, March 26 (TIWN) US President Joe Biden again called his Russian counterpart a "war criminal" due to the Moscow's continued invasion of Kiev.

"The single most important thing that we can do from the outset is to keep the democracies united in our opposition and our effort to curtail the devastation that is occurring at the hands of a man who I quite frankly think is a war criminal," Biden said during a visit with Poland, flanked by Poland’s President Andrzej Duda and USAID Administrator Samantha Powers. "I think it will meet the legal definition of that as well."  Earlier, Biden and Secretary of Defense Lloyd Austin greeted members of the 82nd Airborne division in Rzeszów to thank them for their service.  "Thank you very, very much for all you do. And it's not hyperbole to suggest you're the finest fighting force, not in the world -- in the world. That's not hyperbole," Biden told the room.  Friday’s comments mark the second time in recent weeks that Biden has called Putin a "war criminal", the harshest condemnation of Putin's actions from any US official since the war in Ukraine.
