Polish border guards find six Belarusian soldiers digging under border fence

According to Polish border guards, six Belarusian soldiers were digging under the metal fence on the border. The incident happened near Dubicze Cerkiewne in Hajnowski County, Podlaskie Voivodeship. Previously, migrants regularly attempted to cross from Belarus into Poland illegally. However, after the Polish side installed a 5-meter fence (its construction ends at the end of June), illegal immigrants had a problem getting through it. But why were the military digging there? A Polish patrol caught them at work, and they had to stop doing it.
