Estonia summons a Russian diplomat to protest after three Russian fighter aircraft entered its airspace without permission and stayed there for 12 minutes, Estonia’s Foreign Ministry says. It happened just over a week after NATO planes downed Russian drones over Poland and heightened fears that the war in Ukraine could spill over.

Estonian Foreign Minister Margus Tsahkna says Russia violated Estonian airspace four times this year, “but today’s incursion, involving three fighter aircraft entering our airspace, is unprecedentedly brazen.”

Estonian Defense Minister Hanno Pevkur also says the government had decided “to start consultations among the allies” under NATO’s Article 4, he writes on X, after Russian jets “violated our airspace yet again.”
