Video: Russian nuclear submarines break through metre-thick Arctic ice
With the manoeuvre, Moscow is keen to show its presence in the Arctic region.
Three Russian nuclear submarines simultaneously broke through a thick layer of ice during an exercise in the Arctic, a naval commander said on Friday.
The synchronous maneuver is the first in the history of the Russian Navy, commander-in-chief Nikolai Yevmenov said during a meeting with President Vladimir Putin.
A video released by the military showed the nuclear-powered submarines rising from beneath the 1.5-metre layer of ice, a few hundred metres apart from one another. The crews then appeared from the hatches.
