On Thursday, the patrol of the Belarusian services fired shots in the direction of Polish soldiers who were patrolling the border with the Border Guard. The spokeswoman for the Polish Border Guard Anna Michalska announced this during a press conference regarding the situation on the Polish-Belarussian border.
Anna Michalska stated no one was hurt and that blank ammunition was most probably used.
Poland's Foreign Ministry also summoned Belarus' charge d'affaires over the latter on Friday.
PM Mateusz Morawiecki said on Twitter that "all state powers" were with the border guards and the military protecting the border.
In August, Poland began building a barbed wire fence along its border with Belarus to curb illegal border crossings despite criticism that some migrants were being treated inhumanely.
Poland plans to strengthen its border with a system of motion sensors and cameras, modelling it on the Greek border with Turkey.
