The Polish Border Guard (SG) has recorded more than 3,200 illegal attempts to cross into the country from neighbouring Belarus since the beginning of September.
It said 238 attempts on Thursday alone; a spokesperson told the PAP news agency on Friday.
Meanwhile, a group of refugees who had been stuck in the no man’s land between the Polish and Belarusian border for five weeks remain in a makeshift camp in a forest near the village of Usnarz Gorny.
The migrants were being provided with supplies by the Belarusian side, according to the SG spokesperson.
Although Poland had prevented journalists and aid workers from visiting the group, this information could not be independently verified.
Warsaw has accused Belarusian President Alexander Lukashenko of systematically aiding refugees from war zones to reach the European Union’s (EU’s) external border.
Poland has declared a state of emergency along its border with Belarus, and foreigners as they were barred from travelling to the area.
The Polish military is building a border fence along its 418-kilometre border with Belarus, of which 60 kilometres have already been completed, according to Defence Minister Mariusz Blaszczak.
