Further investigation of a suspected violation of Finnish airspace by a Russian military jet suggests that a total of four Russian planes were involved, according to Finland's Border Guard.
The suspected violation occurred on Monday morning, along the southeast coast, near the town of Loviisa.
According to information available at the time, authorities suspected that a single aircraft flew in Finnish airspace for about two minutes, and was at one point 2.5 kilometres within Finnish territory.
A video published by Russia's Defence Ministry on Tuesday appeared to show two strategic bomber planes being escorted by Russian fighter jets in the Gulf of Finland region. At one point in the video, a Finnish Hornet fighter jet also appeared.
"The environment looks like the southern coast of Finland, and no other countries have Hornet fighters here, so I dare say that it is a Finnish Hornet," military expert Marko Eklund said at the time.
On Saturday, Swedish officials said that a Russian military aircraft briefly violated Swedish airspace east of the Baltic island of Gotland on Friday, Reuters reports.
The Swedish armed forces said that the Russian SU-24 had been issued a warning but failed to respond, after which two Gripen fighter jets were sent up to meet it.
