Ukrainian President Volodymyr Zelenskyy met with Nordic and Baltic leaders at summit in Estonia amid tensions over Ukrainian drones straying into the region. Ukrainian officials apologized, explaining the drones were aimed at Russian military targets but were diverted by interference. Estonia is working with Ukraine on cheaper ways to shoot down drones. Estonia remains a strong supporter of Ukraine against Russia's 4-year-old invasion. Zelenskyy on Tuesday offered Ukraine's expertise and technology to help. Meanwhile, Russia continues its strikes across Ukraine, with casualties reported in Kharkiv and Dnipropetrovsk. In Brussels, European Commission President Ursula von der Leyen said Ukraine is “making extraordinary progress” on reforms to allow it to join the European Union.
