A Russian submarine capable of carrying cruise missiles and torpedoes has been intercepted by the Royal Navy while cruising towards the English Channel.
The vessel was last night being escorted by frigate HMS Kent and is expected to pass the Strait of Dover today.
It is understood that the submarine, Stary Oskol, was first detected in the North Sea where Nato forces are monitoring the waters.
The Ministry of Defence said it will continue to be shadowed by the Type 23 Duke class frigate, which had been taking part in commemorations for the Battle of Jutland centenary.
Defence Secretary Michael Fallon said: "This shows that the Navy is maintaining a vigilant watch in international and territorial waters to keep Britain safe and protect us from potential threats."
Commander Daniel Thomas of HMS Kent said: "Locating this submarine was a combined effort with Nato allies and shadowing such units is routine activity for the Royal Navy.
"We continue to escort the submarine as it conducts its passage, providing a visible presence."
