American President Joe Biden joined leaders around the world Monday in calling for a war crimes trial against Russian President Vladimir Putin. The appeal for justice followed the publication of pictures taken in towns around Kyiv that Russia had attacked. They included many images of dead civilians. “You saw what happened in Bucha,” Biden told reporters on Monday. He called Putin “a war criminal,” adding, “we have to gather all the detail so this can be an actual -- have a war crimes trial.” Several independent news organizations reported and showed images of civilian deaths over the weekend. Ukrainian officials said the bodies of 410 civilians were found in towns around Kiyv after its forces recaptured the area from the Russian military.
