Estonia’s military said in a statement that the Russian MI-8 helicopter entered the country’s airspace in the southeastern Koidula area — not far from the Russian city of Pskov — without permission on Saturday evening.
Russia’s ambassador was summoned and given a note over the incident.
The helicopter was in the NATO member’s airspace for almost two minutes, Estonia’s military said.
It added it had not presented a flight plan, had its transponder switched off and failed to maintain radio contact with Estonian Air Navigation Services.
The alleged intrusion was the second violation of Estonia’s airspace this year.
Last year, Russian aircraft — military and civilian — violated Estonia’s airspace five times, the military said.
On Friday, Russia’s ambassador to Denmark was summoned to the Danish foreign ministry after a Russian military vessel twice violated the country’s territorial waters off the Baltic Sea island of Bornholm.
The incident happened while many Danish lawmakers were on the island for an annual gathering of politicians and lobbyists.
Swedish media reported four of Vladimir Putin’s jets flew over Baltic towards the island of Gotland.TV4, Expressen and Aftonbladet all reported the formation was two Sukhoi Su-24 bombers and two Sukhoi Su-27 fighters.
The Swedish airspace was violated by two Russian SU 27 and two Russian SU 24. The incident was brief and took place east of Gotland, out at sea.
