Speaking later on Friday, Estonian Prime Minister Kristen Michal said his government had “decided to request Nato Article 4 consultations” at an urgent meeting.

“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,” Michal said.

Article 4 of the Nato treaty formally starts urgent consultations within the 32-member alliance, which ties the US and many European nations together on collective defence.

It is the second time in a week that a Nato member has requested Article 4 consultations. Poland did so after Russian drones entered its airspace.

US President Donald Trump told reporters he was due to be briefed on the incident later on Friday.

He said: “I don’t love it. I don’t like when that happens. Could be big trouble. But I’ll let you know later.”

Estonia’s foreign ministry earlier said it had summoned the Russian chargé d’affaires “to lodge a protest” over Friday’s incursion, while top EU diplomat Kaja Kallas described the incident as “an extremely dangerous provocation”.

The minister added Russia had already violated Estonia’s airspace four times in 2025. Estonia shares a border with Russia to the east.

Estonia said the aircraft entered its airspace from the north east and were intercepted by Finnish jets over the Gulf of Finland. Once inside Estonian airspace, Italian F-35 jets, based in Estonia, were deployed under Nato’s Baltic Air Policing mission to escort the aircraft out.

The government said the Russian jets had no flight plans, had their transponders turned off and also did not have two-way radio communication with Estonian air traffic control.

Estonian Defence Minister Hanno Pevkur told the BBC: “It is unprecedented that for 12 minutes the Russians were in our airspace.”

He added that “in this situation, the only right thing to do is to push them out of Estonian airspace”.

Michal also said the Russian incursion showed its war of aggression in Ukraine was not proceeding as the Kremlin had planned.

“The aim is to draw attention and assistance away from Ukraine by forcing Nato countries to focus more on the defence of their own territories,” he added.

In a post on X, Kallas, who is an Estonian national, said the EU “will continue to support our member states in strengthening their defences with European resources”.

She said Russian President Vladimir Putin was “testing the West’s resolve. We must not show weakness”.

Echoing her words, European Commission President Ursula von der Leyen said on X: “We will respond to every provocation with determination while investing in a stronger Eastern flank.”

“As threats escalate, so too will our pressure,” she added.

Estonia’s ambassador to the UK, Sven Sakkov, told the BBC that “clear, practical steps” to increase the protection of airspace above Nato’s eastern flank were needed in light of Friday’s incident.

“If we had to face such times as we are living in now alone, we would be extremely concerned,” he said, adding that Estonians nonetheless felt “determined” to defend themselves.
