US President Joe Biden said that Russian President Vladimir Putin should be held responsible for war crimes, after footage from the city of Bucha in Ukraine showed killed civilians.

You saw what happened in Bucha. Putin is a war criminal, Biden said.

Ukrainian authorities say that they recovered over 400 bodies in the city that was held by Russian forces for weeks. They claim these are civilians who were bound and killed by the Russians. Russia insists that these are fabricated crimes and that Ukraine is to blame.
