A Russian military aircraft is suspected of violating Finland's airspace on June 10, the country's Defense Ministry said in a statement.

"The investigation into the suspect's airspace breach has been launched immediately," Finnish Defense Minister Antti Hakkanen said. The Finnish border guard is investigating and will share more information as the probe continues, according to the Finnish Defense Ministry.

The alleged violation occurred near the city of Porvoo, located about 50 km east of Helsinki. The city lies in the country's far-south, along the Gulf of Finland.

Russia regularly stages provocations on NATO's eastern flank, which includes Poland, Finland, and the Baltic countries. On May 22, two Russian aircraft violated Finnish airspace, while the day prior Polish fighter jets intercepted a Russian Su-24 bomber in international airspace over the Baltic Sea.

Russian aircraft frequently fly from its exclave, Kaliningrad. The jets often disable their transponders, fail to file flight plans, and do not establish contact with regional air traffic control — a pattern NATO officials describe as high-risk behavior.

Since the start of Russia's full-scale invasion, NATO officials have increasingly warned Moscow could attack the alliance's members in the coming years. In anticipation of increased hostilities, Finland has said it expects a Russian military build-up on its borders after the war in Ukraine ends.

On May 19, the New York Times published satellite images which seem to indicate an expansion of military facilities near the Finnish border.

Finland joined NATO in 2023 following the onset of Russia's full-scale war against Ukraine in February 2022 and shares a 1,300-kilometer (800-mile) border with Russia.

NATO countries in Russia's vicinity have intensified their preparations for a possible conflict. Poland and the Baltic countries moved to abandon a treaty banning land mines and are strengthening the borders shared with Russia and its ally Belarus while urging higher defense spending across the alliance.

“We must quickly create space for 1 million people,” Ralph Tiesler, the head of the Germany’s Federal Office of Civil Protection and Disaster Assistance told Suddeutsche Zeitung. “Existing structures must be assessed and adapted without delay.”

President Volodymyr Zelensky arrived in Vilnius on June 2 to participate in a summit of the Bucharest Nine (B9) and the Nordic countries, Zelensky's spokesperson Serhii Nykyforov confirmed for Ukrinform.

The summit is hosted by Lithuanian President Gitanas Nauseda and will also be attended by NATO Secretary General Mark Rutte, who has already arrived, according to Reuters.

The summit is taking place the same day as the second round of Russian-Ukrainian peace talks in Istanbul.

The Vilnius gathering will include leaders from the Baltic countries, Norway, Denmark, Finland, Sweden, Iceland, Poland, Czechia, Slovakia, Hungary, Bulgaria, and Romania. The summit will focus on preparations for the upcoming NATO summit in The Hague later in June and on allied support for Ukraine.

The Hague meeting, which will take place on June 24 and 25, will be the first annual NATO summit since U.S. President Donald Trump returned to the White House.

The alliance faces uncertainty about continued U.S. commitment to NATO as the new administration has signaled plans to reduce its military deployment in Europe.

Trump has also been reluctant to provide new defense aid for Ukraine as he seeks to broker a peace deal between Kyiv and Moscow. Trump's views on Ukraine prompted speculations that Zelensky may not be invited to the summit, or that Ukraine's participation may be scaled down in some way.

The negotiations follow the first round of Istanbul talks, which concluded on May 16 with an agreement on the largest prisoner exchange of the war but without any progress toward a peace deal.
