Two Russian military aircraft are suspected of violating Finnish airspace off the coast of Porvoo on Friday, according to Finland's Ministry of Defence.
"We take the suspected airspace violation seriously, and an investigation is underway," Defence Minister Antti Häkkänen (NCP) said in a statement on Friday evening.
Posting on messaging platform X, the Gulf of Finland Coast Guard said it had launched a preliminary investigation into the incident.
This marks the first known event of its kind since February, when a Russian aircraft last reportedly violated Finnish airspace. At that time, the Russian aircraft was suspected of entering Finnish airspace over the Gulf of Finland, west of Hanko, for a few minutes.
Meanwhile, Polish broadcaster TVP reported that Polish fighter jets intercepted a Russian tactical bomber in international airspace over the Baltic Sea on Thursday. The incident involved a Soviet-era Su-24 aircraft that was located and deterred by two Polish jets at the request of Nato's joint force command.
