BELARUS SEES SABOTAGE FROM WITHIN AS CITIZENS PROTEST AID TO RUSSIA AMID WAR IN UKRAINE: REPORT
Belarus has tightened their border with Poland after an alleged "terrorist" was shot.
Border guards were intensely inspecting vehicles and luggage and scrolling through mobile telephones at the Kazlovichy border crossing with Poland, Viasna said.
Belarusian authorities have conducted large-scale raids and arrests since the Feb. 26 drone attack on a Russian A-50 military plane at an airfield near Minsk. According to Viasna, more than 100 people have already been detained during the raids in Belarus.
Belarus hosts Russian soldiers and equipment, some of which have been deployed in the war in Ukraine.
