At 6:23 p.m. on Monday evening, a An-72 aircraft of the Russian Armed Forces entered into Estonian airspace in the area around Vaindloo Island.
The plane was in Estonian airspace for almost a minute and a half. Its transponder was switched on, however its flight plan had not been submitted and the plane was not in radio contact with Estonian air traffic services.
The Estonian Ministry of Foreign Affairs summoned the Russian ambassador on Tuesday and presented him with a diplomatic note.
The last time a Russian airplane violated Estonian airspace was in June of this year.
