RAF fighter jets have been scrambled twice in less than 48 hours to intercept Russian warplanes that flew close to Nato airspace.
British Typhoons were called into action on two separate occasions this week after Kremlin aircraft approached the border, triggering an alert.
The UK Ministry of Defence (MoD) confirmed Royal Airforce involvement in both interceptions during the past week.
The incident marks the first time the RAF has been deployed under Operation Chessman - a new Nato mission designed to strengthen Europe's air defences.
Ministers have pointed to these confrontations as evidence of Russia's increasingly aggressive testing of the Western military alliance's boundaries.

The interceptions come amid ongoing Ukraine peace negotiations between the US and Russia.
Two RAF Typhoons, based out of Malbork airbase in Poland, were scrambled to intercept a Russian Ilyushin Il-20M intelligence aircraft over the Baltic Sea last Tuesday.
On Thursday, another two Typhoons scrambled from the base, to intercept an unknown aircraft leaving Kaliningrad air space and close to Nato airspace.
The Typhoons are part of a six-strong fleet that was only posted to Poland three weeks ago.

The intercepts come after the Defence Secretary’s visit to Nato last week where he reaffirmed the UK’s "unshakeable commitment" to the alliance.
John Healey also co-chaired a meeting of the Ukraine Defence Contact Group in which more than 50 nations pledged a total of £21 billion of support to Ukraine.
The deployment of six RAF Typhoons and nearly 200 personnel, is the UK’s latest contribution to NATO’s air policing mission, following successful operations in Romania and Iceland last year.
It also represents a landmark in Nato integration, with RAF jets from Lossiemouth in Scotland operating alongside Swedish Gripen fighters.
It is the first time Sweden has contributed fighter aircraft to another Ally’s air policing operation since joining Nato in 2024.
Luke Pollard, the Armed Forces Minister, said: "The UK is unshakeable in its commitment to Nato.

Pollard emphasised the significance of the mission, stating it "shows our ability to operate side by side with Nato's newest member Sweden and to defend the alliance's airspace wherever and whenever needed, keeping us safe at home and strong abroad."
When the planes were initially deployed, Wing Commander Christopher Jacob said they would "defend and deter, standing ready to protect against any threat."
Russia has become increasingly aggressive in probing Nato air defences since its invasion of Ukraine began three years ago.
In November, jets from RAF Lossiemouth intercepted a Russian bomber approaching UK airspace over the North Sea.
The latest incidents occur while the White House and Kremlin remain locked in talks over a potential Ukraine peace deal.
Donald Trump has threatened to pull out of negotiations, suggesting he is losing patience with Moscow's approach.
Putin rejected a US-proposed ceasefire last month that had been accepted by Kyiv.
Russian forces have continued to bomb Ukrainian civilians despite Putin announcing a 30-hour "Easter truce" on Saturday.
Britain and other European nations have formed a "coalition of the willing" to station peacekeepers in Ukraine should a peace deal be reached
PABritain and other European nations have formed a "coalition of the willing" to station peacekeepers in Ukraine should a peace deal be reached.
Under this agreement, troops from the UK and allied nations would be deployed to Ukraine to deter Russia from attempting another invasion.
Sir Keir Starmer is currently working to persuade the United States to provide a "backstop" to this plan.
European nations are meanwhile bolstering their air defences amid signals from Donald Trump suggesting a potential weakening of US military support for the continent.
