As of mid-March, nearly 10 million Ukrainians have been forced to leave their homes as a result of Russia's invasion, which began on February 24. Poland was expected to absorb most of the refugee crisis since the war began. An estimated two million Ukrainian refugees have entered Poland.

Ukraine has said that Russian forces have repeatedly targeted civilian infrastructure, including hospitals, schools, and apartment blocks. The US government accused Russian forces of committing war crimes in Ukraine.

"We've seen numerous credible reports of indiscriminate attacks and attacks deliberately targeting civilians, as well as other atrocities," US Secretary of State Antony Blinken said in a statement on Wednesday.

Biden while visiting troops in Poland again called Putin "a war criminal."

"We're united in our abhorrence of Putin's depraved onslaught, and we'll continue to have their backs as they fight for freedom, democracy, their very survival," Biden previously said.
