Three border guards were killed when a Polish border guard helicopter crashed on the Belarussian side of the border, a spokesman for the Podlaskie fire-brigade rescuers said on Sunday.
The wreckage of the helicopter that disappeared on Saturday afternoon was discovered on Sunday morning in Belarus some 200 meters from the Polish
border, the spokesman was quoted by Polish news agency PAP as saying.
Deputy Polish Interior Minister Adam Rapacki said the crew had no chance to survive the crash as the helicopter was completely destroyed.
The cause of the accident, which occurred during a routine patrol of the border in north-eastern Poland, remains unknown.
