TWO Russian bombers flying in a long-range mission along Europe's western seaboard were intercepted by NATO fighter planes off Scotland.

The two Russian TU-160 Blackjack jets were spotted close to British airspace as they flew from the direction of Norway to northern Spain and back and RAF Lossiemouth-based Royal Air Force Typhoons were among the jets that were scrambled to deal with them.

The report of the NATO jets scrambling comes amid heightened tension between the west and Russia, after the US broke off military cooperation with Moscow over Syria.

The incident involving NATO allies occurred on September 22, but details have been now been revealed by the French Ministry of Defence.

The planes had skirted France's airspace, which extends 12 nautical miles from the coasts.

It began when Norway scrambled two F-16 fighters to respond to a pair of Blackjack bombers flying toward northern Scotland.

It is understood RAF Lossiemouth Typhoons then met and escorted the bombers as they flew west of Shetland.

The RAF said the Russian jets did not enter British air space.

The Russian bombers then skirted the west coast of Ireland and were met by French Rafale jets off the coast of Brittany.

The French Ministry of Defence statement said: "Air policing contributed to the protection of airspace to intercept, and escorted two Russian bombers type TU-160 Blackjack."

Iceland also later noted that Blackjack bombers had flown too close to civil airliners on the same day.

It is understood the RAF scrambles jets in response to probing flights by Russian aircraft several times a year.

The Blackjacks, nicknamed White Swan, because of their slender design, are supersonic strategic bombers designed to carry both nuclear and conventional bombs.

In November, RAF Typhoons intercepted two Blackjacks as they skirted UK airspace on an 8000-mile mission around Europe to fire missile at targets in Syria.

In December last year British military officials held talks with their counterparts in Moscow over "incursions" of Russian aircraft around the UK.

Defence Secretary Sir Michael Fallon said the talks were aimed at finding ways of heading off any "miscalculation or accident".
