Poland’s prime minister says his nation will not hesitate to shoot down objects that violate its airspace and pose a threat. 

Estonia reported that three Russian fighter jets breached its airspace on Friday, heightening concerns among NATO leaders that Moscow is testing the alliance’s readiness and determination, prompting calls from some for a decisive response. The United Nations Security Council is scheduled to convene on Monday to address the incident.

Russia said on Monday the claim its jets violated Estonian airspace was false and designed to stir up tension.

The reported violation over Estonia followed an incident where over 20 Russian drones entered Polish airspace during the night of September 9-10. On Friday, Poland also reported two Russian fighter jets breached the safety zone of the Petrobaltic drilling platform in the Baltic Sea.

‘We will make the decision to shoot down flying objects when they breach our territory and fly over Poland – there is absolutely no discussion about that,’ stated Donald Tusk at a news conference, clarifying that Poland will adopt a more cautious stance towards less clear-cut situations.

‘When encountering situations that aren’t entirely clear, such as the recent flight of Russian fighter jets over the Petrobaltic platform – but without any violation, since these aren’t our territorial waters – it’s crucial to consider carefully before taking actions that could escalate into a severe phase of conflict,’ he further elaborated.

Tusk said that he would also need to be certain that Poland would not be alone if a conflict started to escalate.

‘I also need to be absolutely certain… that all allies will treat this in exactly the same way as we do,’ he said.

Estonia’s claims add to the sense among NATO leaders that Moscow is testing the alliance’s readiness and resolve.

The incident follows a warning from Czech President Petr Pavel, emphasizing the necessity for NATO to be prepared to respond decisively to Russian airspace violations, even if it requires shooting down their aircraft.

Mr Pavel said the organisation should act decisively to stop any breach of allied skies and make clear there are consequences for crossing the line. 

He said: ‘Russia will realise very quickly that they have made a mistake and crossed the acceptable boundaries. Unfortunately, this is teetering on the edge of conflict, but giving in to evil is simply not an option.’

It comes as the UN’s Security Council will meet on Monday for emergency talks after Vladimir Putin’s fighter jets flew into NATO-member Estonia’s airspace, raising fears of World War Three.

Estonia announced on Sunday that the emergency session had been called ‘in response to Russia’s brazen violation of Estonian airspace.’ 

Officials in Tallinn said it is the first time in 34 years of UN membership that the country, a staunch supporter of Ukraine, has formally requested such a meeting.

Set to begin at 15:00 BST, it will discuss what Estonia calls the ‘blatant, reckless, and flagrant violation of NATO airspace’. 

The incursion took place on Friday when three Russian MiG-31 fighters entered Estonian airspace over the Gulf of Finland. 

NATO confirmed that Italian F-35 jets on air defence duty in the Baltics were scrambled, supported by Swedish and Finnish aircraft, to intercept the Russians and warn them off. Moscow denied the allegation.

The incident sparked immediate concern in NATO capitals and Brussels, with both the alliance and the European Union calling it a reckless act of provocation. 

Estonian Prime Minister Kristen Michal condemned the move and said: ‘Such a violation is completely unacceptable. NATO’s response to any provocation must be united and strong.

‘We consider it essential to consult with our allies to ensure shared situational awareness and to agree on our next joint steps.’ 

Ukraine has also requested to attend the meeting on Monday. The country’s foreign minister Andrii Sybiha wrote on X: ‘For the first time in 34 years, Estonia has requested an emergency UNSC meeting. 

‘This shows the unprecedented scale of threats posed by aggressive Russia to the stability of Europe.

Western powers have repeatedly warned that Moscow is playing with fire by pushing into NATO skies, since the alliance’s mutual defence pact obliges all members to act if one is attacked.

The violation came just weeks after fellow NATO member Poland said Russian drones had crossed into its airspace during missile strikes on Ukraine. 

Warsaw branded that episode an ‘act of aggression’ with experts warning that it could have triggered a direct clash between NATO and Russia. The drones struck an elderly couple’s home and demolished its roof. 

If the couple had died, it could have potentially spiralled into World War Three.

Putin has been condemned by Western leaders for provoking NATO countries 

US President Donald Trump added his voice to the outcry on Sunday. Asked whether America would back Poland and the Baltic states if the crisis worsens, he replied: ‘Yeah, I would. I would.’ 

He confirmed he had been briefed on the Estonian incursion and added bluntly: ‘We don’t like it.’

His words were far tougher than his reaction earlier this month to the Polish drone incident, when he had played down the risk by suggesting it ‘could have been a mistake.’

Trump’s stance on Vladimir Putin has long been scrutinised, with critics accusing him of being too close to the Russian leader.

But as the war in Ukraine drags into its fourth year, his tone has hardened. 

Speaking in Britain last Thursday at the close of his state visit, Trump admitted Putin had ‘really let me down’ by refusing to end the bloodshed despite American pushes for peace.

Estonia’s foreign minister, Margus Tsahkna, said Russia’s actions are part of a deliberate pattern.

He said: ‘This violation is part of a broader pattern of escalation by Russia, both regionally and globally. This behaviour requires an international response.’

Tsahkna said that Russia had already entered Estonian airspace four times this year alone. 

Meanwhile, on Sunday, Swedish and German forces said Swedish JAS 39 Gripens and German Eurofighters were deployed over the South Baltic Sea to observe a Russian IL-20 reconnaissance aircraft flying in international airspace without a flight plan. 

German authorities also said the aircraft refused to make contact. 

After the violation, a former RAF commander asked NATO to be specific about the ‘red line’ when it comes to airspace incursions. 

Air Marshal Greg Bagwell wrote on social media: ‘NATO has to be united now, with a clear and unequivocal statement about what will not be tolerated.

‘Right now we don’t know where our red lines are, why should we expect Russia to? And if that red line is crossed then the response must be decisive and ruthless.’

The UK’s defence secretary also issued a chilling warning to Russia. 

He said: ‘Our Typhoons are fully equipped to take out Russian drones that enter Nato airspace. And we will not hesitate to act…’
