Lithuanian lawmakers took shelter underground and air traffic at Vilnius Airport was suspended after a drone entered the country's airspace on May 20, 2024 [1].

The incident highlights the heightened security tensions in the Baltic region, particularly concerning border incursions near Belarus and the readiness of NATO's eastern flank.

Security protocols were triggered when a suspected drone violated Lithuanian airspace [1]. The incursion occurred near the border with Belarus, prompting immediate action at the Lithuanian Parliament building in Vilnius [1]. Members of parliament were forced to move into underground shelters as a precaution while security forces responded to the threat [1].

Simultaneously, the disruption extended to the nation's aviation infrastructure. Officials suspended air traffic at Vilnius Airport to ensure the safety of flights and passengers [1]. The suspension of flights remained in effect while authorities worked to identify and neutralize the airspace violation [1].

The drone alert lasted for about one hour [2]. During this window, the government maintained a high state of alert, coordinating the response between parliamentary security and airport authorities [1].

Lithuania has previously reported various security challenges along its border with Belarus. This latest event underscores the volatility of the region and the persistent threat of unmanned aerial vehicles being used to probe or violate sovereign airspace [1].

This event reflects the ongoing geopolitical friction between NATO members and Belarus. The rapid activation of shelter protocols for lawmakers and the halting of commercial aviation demonstrate that Lithuania views drone incursions not as mere technical glitches, but as significant security threats that necessitate a full-scale emergency response.
