Vilnius Airport reopened on December 1, 2025, after an 11-hour closure due to smuggler balloons from Belarus entering Lithuanian airspace, causing flight cancellations and delays affecting over 7,400 passengers.
On December 1, 2025, Vilnius Airport resumed operations after being shut for nearly eleven hours since 18:09 local time on November 30 due to smuggler balloons from Belarus detected entering Lithuanian airspace. The disruption affected more than 7,400 passengers and 50 flights, resulting in 31 cancellations, ten diversions, and nine delays. Approximately 60 balloons were detected, 40 of which threatened critical approach and departure routes, effectively blocking air traffic. Lithuanian Airports (LTOU) lifted the restrictions at 5:00 local time on Monday, but isolated delays were expected throughout the day. Lithuanian officials view these incursions as a hybrid attack coordinated by Minsk, with smuggling balloons prompting repeated airport shutdowns regionally. Previously, the threat also led Lithuania to close its Belarus border for nearly a month in late October, though it reopened recently. The Prime Minister warned the border closure might be reinstated indefinitely if the hybrid attacks persist. Passengers affected by disruptions are urged to liaise with their airlines directly.
Confidence: High
The event describes aggressive hybrid attacks by Belarusian-launched smuggler balloons entering Lithuanian airspace, causing flight suspensions and disruptions at Vilnius Airport. This is an explicit hostile action targeting Lithuania's civil aviation and border security, thus an aggressor event. There is no indication this report covers defense preparations.
