Estonian military accused the Russian Tu-154 aircraft of violating the Estonian air border last Saturday, reported Estonian Defense Forces.
The report stated that the Tu-154, belonging to the Russian Navy, entered the country's airspace near the island of Vaindloo without permission and was there for less than a minute.
It is noted that the transponder of the aircraft was turned on. As the Press-service of the Defense Forces added, the plane had a flight plan, but there was no radio contact between an aircraft and the Estonian Air Navigation Services.
Estonian Foreign Ministry summoned the Russian Ambassador concerning the incident and gave him a note. According to the Estonian side, it was the first such incident this year.
