Russian President Vladimir Putin led celebrations marking 80th anniversary of the end of World War II with a parade in Moscow's Red Square of 11,000 troops, with World War II-era T-34 tanks alongside advanced weaponry.

As Russian tanks, missiles and drones rumble through Red Square on Friday for the annual Victory Day parade celebrating the Soviet defeat of Nazi Germany, President Vladimir Putin will be joined by at least two dozen world leaders, marking a victory of his own as a leader the West has sought to isolate.
