(International Agencies) – The President of the United States of America, Joe Biden, has called for The President of the Russian Federation, Vladimir Putin, to be tried for war crimes as western leaders prepared a fresh round of economic sanctions against Moscow amid mounting global outrage over claims of civilian killings by Russian soldiers in Ukraine.

"This guy is brutal," Biden said of the Russian leader, adding that he believes Putin "is a war criminal".

Biden's intervention follows the publication of new satellite photos which show bodies lining Bucha's streets during its occupation by Russian forces.

These photos contributed to a mounting international anger over the alleged killing of civilians in Bucha, a town near the capital Kyiv.

Without evidence, Russia said images of atrocities had been staged by Ukraine.
