STORY: Long queues of people formed on what was a sunny May Day public holiday at the entrance to the exhibition, entitled "Trophies of the Russian Army," which is being held outside a museum celebrating the Soviet victory over Nazi Germany in 1945.

On Thursday (May 2), a working day in Russia, the exhibition was still attended by a large number of visitors.

"History is repeating itself," the Russian Defense Ministry said in a statement, adding that the Soviet Union had in 1943 also put on a display of captured tanks and hardware, in this case from the German army.

The Moscow display, which includes U.S., German and French tanks supplied to Ukraine, came days after the U.S. approved a $61 billion aid package for Kyiv and after Russia made some swift but incremental territorial gains in eastern Ukraine at a time when Kyiv's forces say they lack ammo and manpower.
