Lithuania May Invoke NATO Article 4 Over Balloon Incidents, Says Ruginienė

Lithuania is considering the possibility of requesting NATO Article 4 consultations in response to recent aerial incidents, according to Defense Minister Inga Ruginienė, as reported by Reuters.

Article 4, distinct from the more severe Article 5, allows NATO members to request alliance discussions if they perceive a threat to their territorial integrity, political independence, or security. This mechanism has been invoked nine times in NATO’s history, including by Poland and Estonia last September following Russian airspace violations.

Lithuania Assesses Response to Aerial Objects from Belarus After Repeated Airspace Closures

Lithuania temporarily shut down Vilnius Airport again last night after multiple unidentified objects, likely helium balloons, entered its airspace. Authorities suspect smugglers used the balloons to transport contraband from Belarus but accused Russia and Belarus of increasing pressure on Lithuania.

Vilmantas Vitkauskas, head of the National Crisis Management Center, confirmed radar detection of up to 66 objects on Sunday night. Deividas Matulionis, an advisor to President Gitanas Nausėda, described the situation as part of a "hybrid psychological operation" aimed at unsettling the country.

“We expect prompt resolution but also a firm diplomatic response,” Matulionis added.
