Foreign Minister Margus Tsahkna remarked that this was the fourth violation of Estonian airspace by Russia this year. However, he highlighted that the latest incident, involving three fighter jets, was particularly bold. Meanwhile, Estonian Defence Minister Hanno Pevkur announced that the government has resolved to engage in consultations with allies under NATO’s article four, following another breach of their airspace by Russian aircraft.

The North Atlantic Council, which is NATO’s top political decision-making entity, is scheduled to meet early next week for a detailed discussion on the matter, according to NATO spokesperson Allison Hart on Friday.

Article four of the NATO treaty, which is one of the briefest among its 14 provisions, requires member states to consult whenever any party perceives a threat to its territorial integrity, political independence, or security.

President Donald Trump informed reporters that he will be briefed soon by his advisers on the airspace breach. He expressed concern, saying, “I don’t love it,” and added, “I don’t like when that happens. It could be big trouble, but I’ll let you know later.”

Russian officials did not immediately comment.

European governments rattled

The incursion into Polish airspace by Russia marked the most severe cross-border issue involving a NATO member since Russia commenced its extensive invasion of Ukraine in February 2022. Similar incidents, including drone crashes and airspace incursions, have been reported by other NATO countries as well.

The developments have increasingly rattled European governments as U.S.-led efforts to stop the war in Ukraine have come to nothing.

The European Union’s foreign policy chief Kaja Kallas called Friday’s incursion “an extremely dangerous provocation” that “further escalates tensions in the region.”

“On our side, we see that we must show no weakness because weakness is something that invites Russia to do more,” she said. “They are increasingly more dangerous — not only to Ukraine, but also to all the countries around Russia.”

Estonia, along with fellow Baltic states Lithuania and Latvia and neighbouring Poland, are staunch supporters of Ukraine.

Italian F-35 fighter jets respond to Russian incursion

The Russian MIG-31 fighters entered Estonian airspace in the area of Vaindloo Island, a small island located in the Gulf of Finland in the Baltic Sea, the Estonian military said in a separate statement.

The aircraft did not have flight plans and their transponders were turned off, the statement said, nor were the aircraft in two-way radio communication with Estonian air traffic services.

Italian Air Force F-35 fighter jets, currently deployed as part of the NATO Baltic Air Policing Mission, responded to the incident, according to the statement.

In a post on social media, Hart described the incident as “another example of reckless Russian behaviour and NATO’s ability to respond.”

NATO fighter jets scramble hundreds of times most years to intercept aircraft, many of them Russian warplanes in northwest Europe flying too close to the airspace of its member countries, but it’s rarer for planes to cross the boundary.

Dozens of NATO jets are on round-the-clock alert across Europe to respond to incidents such as unannounced military flights or civilian planes losing communication with air traffic controllers.

Separately, Maj. Taavi Karotamm, spokesperson for the Estonian Defence Forces, told The Associated Press the Russian planes flew parallel to the Estonian border from east to west and did not head toward the capital, Tallinn.

Karotamm said the reason for the border violation is unknown, but added that it may have been to “shift the focus of NATO and its members on to defending itself, rather than bolstering Ukrainian defence.”

“Russia’s increasingly extensive testing of boundaries and growing aggressiveness must be met with a swift increase in political and economic pressure,” Tsakhna, the foreign minister, said.

The Russian charge d’affaires was summoned and given a protest note, a ministry statement said.

British spy chief says ‘no evidence’ Putin wants peace

Earlier Friday, the head of Britain’s foreign intelligence agency said there is “absolutely no evidence” that Russia’s President Vladimir Putin wants to negotiate peace in Ukraine.

Richard Moore, chief of the Secret Intelligence Service, or MI6 as it is more commonly known, said Putin was “stringing us along.”

“He seeks to impose his imperial will by all means at his disposal. But he cannot succeed,” Moore said. “Bluntly, Putin has bitten off more than he can chew. He thought he was going to win an easy victory. But he — and many others — underestimated the Ukrainians.”

The war has continued unabated in the three years since Russia invaded its neighbour. Ukraine has accepted proposals for a ceasefire and a summit meeting, but Moscow has demurred.

US President Donald Trump said Thursday during a state visit to the United Kingdom that Putin “has really let me down” in peace efforts.

Putin is ‘mortgaging the future’ of Russia

Moore was speaking at the British consulate in Istanbul after five years as head of MI6. He leaves the post at the end of September. The agency will then get its first female chief.

Moore said the invasion had strengthened Ukrainian national identity and accelerated its westward trajectory, as well as pushing Sweden and Finland to join NATO.

“Putin has sought to convince the world that Russian victory is inevitable. But he lies. He lies to the world. He lies to his people. Perhaps he even lies to himself,” Moore told a news conference.

He said that Putin was “mortgaging his country’s future for his own personal legacy and a distorted version of history” and the war was “accelerating this decline.”

Analysts say Putin believes he can outlast the political commitment of Ukraine’s Western partners and win a protracted war of attrition by wearing down Ukraine’s smaller army with sheer weight of numbers.

Ukraine, meanwhile, is racing to expand its defence cooperation with other countries and secure billions of dollars of investment in its domestic weapons industry.

MI6 unveils dark web portal

The spy chief was speaking as MI6 unveiled a dark web portal to allow potential intelligence providers to contact the service. Dubbed “Silent Courier,” the secure messaging platform aims to recruit new spies for the UK, including in Russia.

“To those men and women in Russia who have truths to share and the courage to share them, I invite you to contact MI6,” Moore said.

Not just Russians but “anyone, anywhere in the world” would be able to use the portal to offer sensitive information on terrorism or “hostile intelligence activity,” he said.
