RAF Typhoons have been launched to intercept two Russian aircraft near UK airspace, the Ministry of Defence (MoD) has confirmed.
The incident came as Britain hosts a Nato exercise in northern Scotland involving more than 50 warships.
The MoD said: "RAF Typhoon fighter aircraft were launched from RAF Lossiemouth after Russian aircraft were identified flying close to UK airspace.
"The Russian planes are being escorted by the RAF in the UK area of interest."
It is the latest of several similar incidents involving Russian military aircraft flying close to UK airspace.
There has been no immediate comment by the Russian defence ministry but it has denied any wrongdoing in previous incidents and described its air patrols as "routine".
