A state-of-the-art Russian tank which was shown to the public for the first time earlier this month has ground to a halt during the final Victory Day rehearsal.
The tank, T-14 Armata, is said to surpass all Western versions because of its remotely controlled cannon and the protection it offers to its crew.
Weaponry was rolling across central Moscow in the dress rehearsal of the May 9 military parade as Russia commemorates the 70th anniversary of victory over Nazi Germany in the Second World War.
One of the tanks moving on Red Square suddenly stopped while others drove on. The engine was still rumbling but it would not move.
After an attempt to tow it failed, the T-14 rolled away under its own steam about 15 minutes later.
