In response, Belarus has protested the Polish decision to halt border crossings during the period of Russia-Belarus military drills Zapad-2025, according to the Belarusian Foreign Ministry on Tuesday.

The Belarusian side has summoned Poland's charge d'affaires Krzysztof Ozanna in Minsk and issued a verbal protest.

The Belarusian Foreign Ministry said Poland's unilateral move is expected to affect the entire EU-Belarus border, disrupting the movement of people and goods.
