Russia and Belarus have launched a large military exercise near NATO borders, alarming Poland and prompting serious security measures at the border.

The exercise, named 'Zapad-2025', is described by Moscow as a step to strengthen military cooperation. However, Poland has mobilized troops due to border violations.

Polish Prime Minister Donald Tusk described the exercises as extremely aggressive and provocative, announcing that 40,000 soldiers would be deployed for national security.

Ukrainian President Zelensky called on the US and allies to respond to Russia following the tensions in Poland. This situation could affect security balances in the region.

The proximity of the exercises to the Polish border is being closely monitored by Western countries, which may escalate tensions between NATO and Russia.
