Military jets in the north-east have been scrambled to intercept Russian bombers approaching UK airspace.
Typhoons from RAF Lossiemouth were launched yesterday to track two long-range Blackjack planes that were not talking to air traffic control.
The Ministry of Defence says the lack of communication made the bombers a potential hazard to other aviation in the area.
The RAF jets intercepted the Russians over the North Sea before escorting them to the north, away from the UK. At no time did they enter the country’s airspace.
Defence Secretary Gavin Williamson said: “Russian bombers probing UK airspace is another reminder of the very serious military challenge that Russia poses us today.
“We will not hesitate to continually defend our skies from acts of aggression. Once again the rapid reactions of our RAF have demonstrated how vital our Armed Forces are in protecting Britain.”
Typhoons at RAF Lossiemouth are on continuous alert to track aircraft approaching the UK.
