The Situation Room with Wolf Blitzer

U.S. Defense Secretary Lloyd Austin said Europe is facing its biggest challenge in generations as Russian forces make "incremental gains" in South Ukraine and as Russia has used "some brutal, savage techniques in terms of the way that they've been targeting civilian populations." Chairman of the Armed Services Committee Rep. Adam Smith joins to discuss the comments and whether Russia has become more brutal in its attack. 

And, nearly 10 million people in Ukraine have been displaced from their homes since Russia began its invasion. CNN reporters take you to a train station in Poland and a refugee shelter in Lviv to see the situation on the ground.
