Estonia has requested a consultation with other NATO members after Russian warplanes violated its airspace on Friday morning.

Three Russian MiG-31 fighter jets entered the Estonian skies without permission and remained there for a total of 12 minutes over the Gulf of Finland, the government said.

Italy, Finland and Sweden scrambled jets under NATO's mission to bolster its eastern flank. A NATO spokesperson stated it was yet another example of reckless Russian behaviour and NATO's ability to respond.

Russia denied violating Estonian airspace, contributing to a growing list of border tensions including recent incursions into Polish and Romanian airspaces.

Article 4 of the NATO treaty formally initiates urgent consultations within the alliance, which consists of 32 member nations dedicated to collective defense. This marks the second Article 4 request this month, following a similar plea from Poland.

Estonian Prime Minister Kristen Michal emphasized the need for a unified NATO response to any provocation, stating, It is essential to consult with our allies to ensure shared situational awareness and to establish our next joint steps.

US President Donald Trump expressed disapproval of the situation, warning it could lead to big trouble. Czech President Petr Pavel suggested NATO should consider more assertive actions, including shooting down intruding aircraft.

This incident signifies the fifth violation of Estonian airspace by Russian planes in 2023, prompting NATO fighter jets to escort the Russian jets out of the area.

Russian officials claimed their aircraft were operating on a scheduled flight and adhered to international regulations. However, Estonian authorities noted the jets operated without flight plans and failed to communicate with air traffic control.

As discussions surrounding NATO's strategic response continue, the tensions remain a focal point for European defense strategies as the situation evolves.
