Royal Navy sailors were watching the ship through binoculars, and using radar to track her course and speed.

Commander Trish Kohn, Commanding Officer of HMS Sutherland, said: "This transit is being continually monitored through a co-ordinated response between the Royal Navy and our Nato partners.
"The transit of Russian ships from the Mediterranean to their northern ports is not unusual, but the Royal Navy is ready at all times to protect UK territorial waters."
