Estonia has requested a consultation of NATO allies after three Russian fighter jets violated its airspace on Friday in what officials described as an “unprecedented brazen” 12-minute incursion.

While Russian aircraft have crossed Estonian airspace before, such incidents have typically lasted only seconds. The duration of Friday’s violation was unusual and immediately drew international reaction.

Estonian President said air defense “must be a priority,” while European Union foreign policy chief Kaja Kallas condemned the incident as a “dangerous provocation.” U.S. President Donald Trump also weighed in, warning the breach “could be big trouble.”

Russia’s Defense Ministry denied the allegation, claiming the flight was in line with international aviation rules and “did not violate Estonia’s borders.”

The incident comes amid heightened regional tensions. Poland confirmed it had deployed aircraft overnight in response to a large-scale Russian missile and drone barrage against Ukraine. At least three people were killed and dozens injured in the strikes, according to Ukrainian President Volodymyr Zelenskyy.

The Estonian government has urged NATO allies to coordinate a strong response, warning that continued airspace violations pose a direct challenge to the alliance’s security.
