The two-day teleconference meeting of NATO defence ministers started earlier in the day.
The North Atlantic Council, the chief political decision-making authority within the North Atlantic Treaty Organisation (NATO), held a meeting at the level of the defence ministers via a secure video conference, addressing the issues of resilience, missions and operations.
Russia has repeatedly pointed to increased activities of NATO forces close to its border. One example occurred earlier in June, when Russia's Defence Ministry registered heightened activity of the US and NATO forces near its borders, including the Defender-Europe 20 military exercise and the first naval exercise in the Barents Sea since the end of the Cold War.
On Sunday, Russian President Vladimir Putin affirmed the country's leadership in cutting-edge weaponry, including hypersonic weapons.
