Estonia has summoned a Russian diplomat to protest after three Russian fighter jets entered its airspace without permission. The Foreign Ministry said the incursion on Friday lasted 12 minutes. This is the fifth time this year that Russia has violated Estonian airspace, but the Foreign Minister called this incident "unprecedentedly brazen." The airspace violation comes just over a week after NATO planes downed Russian drones over Poland, raising concerns about the war in Ukraine spilling over. Russian officials have not yet commented on the incident.
