The U.S. Embassy in Kyiv says Moscow could launch a major attack on Ukraine, despite President Vladimir Putin's truce.

Russian President Vladimir Putin has taken center stage at Russia’s Victory Day parade on Friday, surrounding himself by friendly world leaders in a highly choreographed show designed to show the Western world that Russia is far from isolated.

Vladimir Putin has led Russia's Victory Day commemorations with a parade in Red Square and heightened security after days of Ukrainian strikes targeting the capital. China's Xi Jinping joined Putin as the Russian president told thousands of soldiers and more than 20 international leaders that Russia remembered the lessons of World War Two.
