Drones, shelters and Lukashenko's pledge on 21 May

Summary
A look back at a day when Belarus's leader ruled out joining the war while Baltic states dealt with stray drones.
What did Minsk's message amount to on 21 May 2026, when Belarusian president Alexander Lukashenko said his country would not join the war against Ukraine and that he was ready to meet Ukrainian president Volodymyr Zelenskyy?
The statement came as the security picture along NATO's eastern flank was unsettled. On 20 May, Lithuania issued an air raid alert in Vilnius after the military detected a drone signal near the Belarusian border. It was the first time since Russia's full-scale invasion in 2022 that an EU and NATO member state had ordered the general population to take shelter.
On 19 May, Estonia reported that a Romanian NATO F-16 had shot down a drone over Estonian territory. The drone was suspected to be of Ukrainian origin and to have been affected by Russian electronic warfare. Two alliance members in the Baltic region had therefore dealt with drone incidents within days of each other.
Belarus's position
Belarus is a close ally of Russia and a member of the Union State with it. Before the 2022 offensive it allowed Russian forces to hold drills on its territory, and Russian troops then stayed on. Russia staged part of its invasion from Belarus, giving it the shortest land route to Kyiv. Those forces withdrew within two months, ending land-based operations from Belarusian territory, and Ukraine recaptured its side of the border region. The border has remained tense, and Ukraine has closed its checkpoints into Belarus except for special cases.
Against that background, Lukashenko's words on 21 May combined a refusal to enter the war with an offer of direct contact with Kyiv's leadership. Whether the offer would lead anywhere was not settled that day.
The front in the south
The fighting itself continued on 21 May. Forces of the Alpha Group of Ukraine's Secret Service struck a Russian Federal Security Service headquarters in Kherson Oblast. Russia has occupied parts of the region since it invaded from Crimea on 24 February 2022.
What the day showed
Taken together, the events of 19 to 21 May showed two parallel concerns: the war's spillover into the airspace of NATO and EU states near Belarus and the Baltic, and the diplomatic positioning of Belarus. Alert measures in Vilnius and the intercept over Estonia were responses to drone activity, while Lukashenko's remarks were a statement of intent. Ukraine's strike in Kherson Oblast meanwhile underlined that active operations went on in the south.
