A Russian reconnaissance aircraft approaching over the Baltic Sea has alerted the German Air Force.

As a reaction, two Eurofighters from the Laage air base in Mecklenburg-Western Pomerania rose to an alarm start on Saturday, as the German Press Agency learned.

The Russian machine was identified in international airspace off the island of Rügen.

The alarm squad from the two German machines accompanied the Russian aircraft in international airspace away from Germany.

Denmark had already summoned the Russian ambassador to the Foreign Ministry for an interview.

Foreign Minister Jeppe Kofod justified this on Sunday by saying that a Russian military aircraft had entered Danish airspace.

According to Swedish information, a Russian AN-30 propeller aircraft also violated Swedish airspace east of the Danish Baltic Sea island of Bornholm.

Four Russian fighter jets entered the airspace over Sweden in early March.

The Swedish Ministry of Defense in Stockholm described the incident as "completely unacceptable".

Especially in view of the "general security situation", the airspace violation was "very inappropriate", said Defense Minister Peter Hultqvist, according to the television station SVT.

Airspace violations have also recently occurred over direct NATO territory, reports Die Welt.

As the alliance announced, in the past four days there have been several situations in which Russian aircraft have invaded NATO airspace over the Baltic and Black Seas.

"Allied warplanes were on their way to pursue and intercept the Russian planes."
