The suspected violation happened at 6.40am and the jets were westbound, communications chief Kristian Vakkuri told Reuters, adding the aircraft were in Finnish airspace for two minutes.
“The depth of the suspected violation into Finnish airspace was 1km,” he said, but would not elaborate on whether the planes were escorted out.
The Finnish airforce identified the planes and the Border Guard has already launched an investigation into the violation, the ministry statement added.
Russia’s defence ministry today was cited by Interfax as saying it had relocated three MiG-31E warplanes equipped with Kinzhal hypersonic missiles to its Kaliningrad region, a Russian Baltic coast exclave between Poland and Lithuania.
