Russia's growing aggression prompts NATO warning as recent railway blast in Poland and airspace violations signal escalating security threats across Europe.

NATO chief Mark Rutte warned members of the military alliance must treat the threat posed by Moscow more urgently as they may be "Russia's next target."

During a visit to Vietnam, Shoigu, who is now secretary of Russia ’s Security Council, told reporters of the emergence of "embryos of NATO in the East," which could threaten Russia and members of ASEAN (Association of South East Asian Nations). Newsweek has contacted NATO for comment.

Jets and air defense systems were involved in the response, Warsaw said.

For NATO, boosting support for Ukraine also is viewed as a way to keep Russia on its heels. While U.S. President Donald Trump attempts to negotiate a peace deal between the two countries, Rutte said allies must keep the pressure on Moscow by getting more arms into the hands of Ukrainian troops.

A British naval supply ship with an on-board helicopter was deployed to track the stealthy Kilo-class submarine Krasnodar, the Royal Navy said.

The central bank said on Friday that Euroclear, which holds €185bn of the €210bn in Russian assets frozen by Europe, had “made it impossible to access funds and securities belonging to the Bank of Russia” through “illegal actions”.

In a speech in Berlin, Rutte said too many allies of the military alliance did not feel the urgency of Russia's threat in Europe and that they must rapidly increase defence spending and production to prevent a war on the scale of that seen by past generations.
