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.

Russia wants to test NATO's resolve by hostile steps beyond Ukraine, as some Russian officials believe the alliance's collective defense principle no longer works, German intelligence chief Bruno Kahl told the Table Media news outlet in an interview published on June 9.

"There are people in Moscow who no longer believe that NATO's Article 5 works. And they would like to test it," Kahl said in the podcast interview.

The comments come as NATO Secretary General Mark Rutte warned that Russia could be ready to launch an attack against the alliance within five years. Such stark warnings have become increasingly common since Moscow's full-scale invasion of Ukraine in 2022.

The chief of Germany's Federal Intelligence Service (BND) noted that Moscow sees its war in Ukraine as "only a step on its path westward." Citing intelligence sources, he said Russia may seek to start a lower-intensity confrontation that will test the U.S.'s willingness to fulfill its obligations under Article 5.

"They don't need to send tanks for that," Kahl noted. "They just have to send 'little green men' to Estonia to defend the allegedly oppressed Russian minority."

Article 5 refers to a key principle of the North Atlantic Treaty, which obliges all members to treat an attack on one member as an attack on all and provide assistance. The article has been invoked only once, following the September 11 terrorist attacks against the U.S. in 2001.

The term "little green men" was first used in reference to Russian soldiers without insignia who seized key strategic facilities in Crimea in 2014 in the opening phase of the Russian occupation of the Ukrainian peninsula.

Concerns among NATO members about a potential Russian aggression and Washington's commitment to the alliance have grown since U.S. President Donald Trump took office in January.

The new administration has signaled plans to reduce military presence in Europe, and Trump has even directly challenged the collective defense principle by saying the U.S. would not defend NATO members who do not invest sufficiently in their military capabilities.

New German Chancellor Friedrich Merz traveled to Washington last week to meet Trump and discuss joint support for Ukraine and NATO's future. While the talks proceeded relatively smoothly, the German chancellor failed to obtain any concrete commitments from Trump.

Multiple Ukrainian and Western officials have warned that Russia may be preparing for an open confrontation with NATO after ending its war against Kyiv. The preparations may pick up pace if Western sanctions are lifted as part of a potential peace deal, Ukrainian intelligence said.

Russia produces as much ammunition in three months as NATO does in a year, posing serious risks for the alliance, NATO Secretary General Mark Rutte said on June 9 at Chatham House in London.

"The capabilities of (Vladimir) Putin's war machine are speeding up, not slowing down," Rutte said. "Russia is reconstituting its forces with Chinese technology and producing more weapons faster than we thought."

Rutte's statement comes amid mounting tensions between the alliance and Russia and an increasingly uncertain U.S. commitment to European security.

According to Rutte, Russia is restoring its military potential with the help of China, Iran, and North Korea. This year, the Russian industrial complex is expected to roll out 1,500 tanks, 3,000 armored vehicles, and 200 Iskander missiles, NATO chief said.

"Russia could be ready to use military force against NATO within five years," Rutte said. "Let's not kid ourselves."

"We are all on the eastern flank now. The new generation of Russian missiles travels at the speed of sound. The distance between European capitals is only a matter of minutes. There is no longer east or west. There is just NATO," he added.

When asked whether a long-term truce in Ukraine's war against Russia would allow the latter to stockpile even more weapons and increase the risks to NATO, Rutte said: "That's a statement of fact."

"Our assumption at the moment is that even whilst the war against Ukraine is continuing, they (Russian forces) are still able to increase stockpiles slightly, but that's debatable," Rutte added.

Russia's full-scale invasion of Ukraine in 2022 prompted European countries to hike defense spending in order to revive their military capabilities, which atrophied after decades of disarmament following the Cold War.

The matter gained more urgency after signals that the U.S., the most powerful military in NATO, plans to scale down its presence in Europe as President Donald Trump shifts strategic focus to the Asia-Pacific region.

Ukrainian foreign intelligence chief Oleh Ivashchenko recently warned that Russia will be able to replenish its forces between two and four years after the war in Ukraine, allowing it to launch aggression against Europe.

Germany is planning to quickly expand it network of air raid shelters and bunkers, in preparation for a potential Russian attack on the country, Ralph Tiesler, the head of the Germany's Federal Office of Civil Protection and Disaster Assistance said.

"For a long time, there was a widespread belief in Germany that war was not a scenario for which we needed to prepare. That has changed. We are concerned about the risk of a major war of aggression in Europe," Tiesler told the German Suddeutsche Zeitung news outlet on June 5.

Tiesler, the official in charge of civilian protection in Germany, said that only 580 of the country's 2,000 cold war-era bunkers were in working order. In its current condition, the shelters would house 480,000 people, a small fraction of the country's population that total 83 million people.

"We must quickly create space for 1 million people," Tiesler said. "Existing structures must be assessed and adapted without delay," warning that solely constructing new shelters would take too long.

The focus on revamping shelters comes amid ongoing fears that Russia may attack a NATO country within the next decade.

Germany's Defense Chief Carsten Breuer told BBC on June 1 that allies need to be prepared for an attack within the next four years.

"There's an intent and there's a build up of the stocks," Breuer said. "This is what the analysts are assessing - in 2029. So we have to be ready by 2029... If you ask me now, is this a guarantee that's not earlier than 2029? I would say no, it's not. So we must be able to fight tonight."

Breuer's comments were the latest in a series of increasingly dire warnings from Western leaders and defense officials about the threat emanating from Russia and Europe's current lack of preparedness.

Tiesler said that Germany would need to spend at least 10 billion euros ($11.4 billion) to cover civil defense needs over the next four years, and 30 billion euros ($34 billion) over the next 10 years. Tiesler's office is expected to produce a detailed plan to the shelters' expansion, as well as addition civil defense needs this summer.

As concerns as to where Russia may launch an initial incursion into NATO territory mount, Russia has continued to restructure its military presence along its Baltic flank. Analysts and military experts believe that Russia may launch on initial attack on a country in the Baltic Sea region, given its strategic positioning and surroundings, including the Russian exclave of Kaliningrad.

The North Atlantic Treaty Organization (NATO) is urging European member nations to increase their ground-based air defense capacities by five times in order to mount a more effective response to the threat of Russian aggression, Bloomberg reported on June 3, citing sources familiar with the matter.

The reported request is NATO's latest bid to shore up European security amid heightened tensions with Russia and an increasingly uncertain U.S. commitment to Europe's defense.

NATO defense ministers will discuss the air defense boost at a gathering in Brussels on June 5, sources told Bloomberg on the condition of anonymity. A number of proposed defense increases are on the agenda for the meeting, which will set the stage for the NATO summit in The Hague on June 24-25.

The air defense target is a collective goal for NATO's European members, with varying levels from individual states, sources said. The timeframe for the fivefold increase is not yet clear.  

According to one senior European military official, NATO members face a shortage of ground-based air-defense systems to protect against drones, missiles, and fighter jets, having shifted away from these systems after the end of the Cold War.

"We are not at war, but we're not at peace either," NATO Secretary General Mark Rutte said during the Vilnius summit of the Bucharest Nine (B9) and the Nordic countries on June 2.

"We must continue to strengthen our deterrence and defense and that means pivoting toward a full war-fighting readiness."

Russia's full-scale invasion of Ukraine in 2022 prompted European countries to hike defense spending in order to revive their military capabilities following decades of disarmament.

Ukrainian and Western officials have sounded the alarm on Russia's threat to both NATO and Europe, warning that an open clash between Moscow and NATO could break out two to four years after the full-scale war against Ukraine ends.

NATO is not holding any active discussions on Russia's demand that the alliance halt its eastward expansion,  Radio Free Europe / Radio Liberty wrote, citing several undisclosed NATO officials and diplomats.

Speaking on condition of anonymity, the NATO officials said that the issue of NATO's potential non-enlargement has not been raised at any recent, or even earlier, alliance meetings. One official called it "perhaps just an academic discussion," noting that any such decision would require full consensus among NATO members.

The clarification comes after Reuters reported on May 28 that Russian President Vladimir Putin's conditions for ending the war in Ukraine include receiving a written commitment from Western leaders to cease NATO's expansion.

Russian propaganda for years insisted that Ukraine's ambition to join NATO was a major trigger for its invasion. Russia's military aggression against Ukraine started in 2014 with the annexation of Crimea and the war in eastern Ukraine, at a time when Ukraine's chances and desires of joining the alliance were low.

According to NATO sources cited by Radio Liberty, the written pledge Moscow demands is unrealistic. "It’s not something they (Russia) can just get," one diplomat said, pointing to international agreements that enshrine every nation's right to freely choose its alliances — including the North Atlantic Treaty of 1949, the 1969 Vienna Convention on the Law of Treaties, and the 1975 Helsinki Final Act.

A separate source referenced the NATO-Russia Founding Act of 1997, a document some consider obsolete but still formally existing, which affirms respect for the sovereignty and territorial integrity of all states and upholds the principle of self-determination.

U.S. Special Envoy Keith Kellogg said in a May 29 interview with ABC News that NATO's eastward expansion is a "fair" concern for Putin. He also emphasized that Ukraine's membership in the alliance is "not on the table."

U.S. President Donald Trump has also repeatedly echoed Moscow's narrative that Ukraine's efforts to join NATO have been one of the root causes of the full-scale invasion.

In March, Foreign Minister Andrii Sybiha firmly opposed any limitations on Ukraine's right to join international organizations, specifically NATO and the European Union, as a condition for reaching a potential peace agreement.

Ukraine applied for NATO membership in September 2022, months after the outbreak of the full-scale war. The country has not received a formal invitation, as the 32 members have not reached a consensus.

NATO wants Germany to contribute seven more brigades, or roughly 40,000 troops, to boost collective defense against Russia, Bloomberg and Reuters reported on May 28, citing their sources.

The news comes amid mounting tensions between the alliance and Russia and an increasingly uncertain U.S. commitment to European security.

The alliance's overall demand for the number of brigades provided by member states could go from 80 to between 120 and 130, an undisclosed senior official told Reuters.

Germany agreed to provide 10 brigades to NATO by 2030. It currently fields nine brigades — each comprising around 5,000 soldiers — including one new formation stationed in Lithuania.

Though no firm date for implementing the changes has been set, 2030 has been mentioned as a preferred deadline, Bloomberg reported.

Allied defense ministers are expected to discuss the matter during a meeting in Brussels next week.

Russia's full-scale invasion of Ukraine in 2022 prompted European countries to hike defense spending in order to revive their military capabilities, which atrophied after decades of disarmament following the Cold War.

The matter gained more urgency after signals that the U.S., the most powerful military in NATO, plans to scale down its presence in Europe as President Donald Trump shifts strategic focus to the Asia-Pacific region.
