Russian military planes briefly violated Lithuania’s airspace Thursday evening, the Lithuanian president said, condemning what he called a blatant breach of the territorial integrity of his European Union and NATO-member country.

Lithuania’s foreign ministry planned to summon Russian Embassy representatives in the Lithuanian capital of Vilnius to protest the violation, President Gitanas Nausėda said in a post on the social media platform X.

“This is a blatant breach of international law and territorial integrity of Lithuania,” Nausėda wrote on X. “Once again, it confirms the importance of strengthening European air defence readiness.”
