This morning, an RAF Voyager and two RAF Typhoons were scrambled from a number of different bases. The three planes are now in a holding pattern near the Outer Hebridies. It comes after a spate of incidents involving Russian aircraft nearing UK or NATO airspace.
In February this year, RAF jets were scrambled after aircraft were spotted flying near Shetland.
The rival planes were unidentified but believed to be Russian bombers.
They remained outside UK airspace so were not intercepted.
However it matches a pattern popular with Russia leader Vladimir Putin, who likes to test the patience and nerve of his rivals with provocative flight paths.
