On 19 September 2025, three Russian MiG-31 fighter jets violated Estonian airspace over the Gulf of Finland without permission, remaining there for 12 minutes. Estonia requested an urgent NATO consultation under Article 4. Italian, Finnish, and Swedish jets scrambled to respond under NATO's Baltic Air Policing mission. Russian jets had no flight plans, turned off transponders, and lacked two-way radio communication. Russia denied the airspace violation, claiming jets flew over neutral Baltic waters near Estonia. This was Estonia's fifth Russian airspace violation of 2025. The incident occurs amid increased regional tensions following Russian drone incursions into Polish and Romanian airspace. NATO pledges to reinforce eastern flank with additional troops and fighter jets from the UK, France, Germany, and Denmark. Estonian officials and NATO members emphasize the need for a united and strong response to Russian provocations.
