Russian aircraft have been intercepted by Royal Air Force Typhoon fighter jets for the second time this week.
The incident, which took place over the Baltic Sea, marks the second scrambling in just 48 hours for the RAF detachment.
6 Squadron, which is working alongside Spanish Air Force F-18s at Šiauliai Air Base in northern Lithuania on the NATO air policing mission, intercepted a Russian Il-20 COOT and two Russian Su-27s during the flight.
The Typhoons joined the mission, also known as Operation Azotize, began earlier this year.
One of the pilots on Quick Reaction Alert duty when the scramble was called outlined the more challenging aspects of the second intercept.
"This mission was more complex, as there were more aircraft to manage of different types and flying at different speeds," they said.
"We are always ready to react in support of the NATO mission."
Air Vice Marshal Ian Duguid, The Air Officer Commanding 11 Group said: "Today saw the second RAF intercept of Russian aircraft over the Baltic.
"This remains routine activity, however it must be stressed that the RAF as part of NATO are conducting these activities to ensure that all flights are conducted within internationally accepted aviation rules.
"When this does not happen NATO will intercept and investigate.
"I congratulate all of our deployed personnel in Lithuania for the professional way that they are conducting the mission in conjunction with our Lithuanian and Spanish Allies, they bring great credit to the service," he added.
