A helicopter from the Polish army "violated the Belarusian border," the Border Control Center of Belarus said in a statement published on its Telegram account.
"In the afternoon, September 1, Belarusian border guards recorded a violation of the airspace of Belarus by Poland in Berastavitski district, Hrodna voblast," the military said.
In addition, the statement noted that the Mi-24 copter crossed at an "extremely low altitude." It then flew into the national territory as much as 1,200 meters and then returned.
