On May 21, 2026, Latvia and Lithuania detected unauthorized drone activity in their airspace, leading to the issuance of air alerts and the scrambling of NATO fighter jets. The Latvian National Armed Forces confirmed at least one drone was spotted, resulting in air alerts across several municipalities, including Ludza and Rēzekne.

This incident marked the third consecutive day that Latvia has declared a drone-related alert, indicative of escalating security concerns in the region. Residents were advised to remain indoors and follow safety protocols to mitigate exposure to potential blasts. The armed forces have bolstered their air defense capabilities along the eastern border with additional military resources.

In Lithuania, military jets were deployed to search for two drones near its borders, where air raid sirens were activated to warn civilians of possible danger. Local officials underscored the likelihood of continued drone incursions as a result of ongoing hostilities in the region, particularly due to Russia’s aggression in Ukraine.

Recent investigations suggest that Russian electronic jamming has played a role in misdirecting Ukrainian drones into NATO airspace. Latvia's military noted this risk, stating, “As long as Russia’s aggression in Ukraine continues, there is a possibility of repeated incidents where foreign unmanned aerial vehicles enter or approach Latvian airspace.”

The political ramifications of the ongoing incursions are significant, as Latvia's government recently resigned due to pressures related to its handling of security situations amid drone incursions. The situation gained international attention, especially after a NATO fighter jet successfully downed a suspected Ukrainian drone over Estonia on May 19, marking a heightened state of alert across the Baltic states.

The incidents highlight the fragility of airspace security in the Baltic region and the ongoing tensions stemming from the war in Ukraine, challenging the stability and safety of NATO's eastern flank. Both Latvian and Lithuanian authorities continue to assess the situation and coordinate their responses with NATO to safeguard against potential threats from drones entering their airspace.
