The Finnish Defense Ministry said in a statement released Wednesday two Russian military aircraft crossed into Finland's airspace.
The ministry said the incident took place early Tuesday over the Gulf of Finland.
The Finnish Air Force dispatched Hornet fighter jets to identify the intruders, the statement reads.
The Russian Defense Ministry admitted their aircraft were in the vicinity of Finland but denied they entered Finnish airspace, RIA Novosti said.
This is the second incident of its kind in a month, RIA Novosti said, and the Russian government denied Finland's last accusation, as well.
In 2008, Finland announced plans to purchase 12 new radar systems due to alleged, repeated invasions of its airspace by Russian jets.
