Wagner fighters in Belarus could pose as migrants and enter the EU, Polish Prime Minister Mateusz Morawiecki has warned.
Wagner could also facilitate illegal migration from Belarus, which Poland describes as “hybrid warfare”, he says.
About 100 Wagner troops have moved near the city of Grodno, close to the Polish and Lithuanian borders, the PM added.
Some Wagner troops have moved to Belarus under a deal to end a brief mutiny in Russia in June.
Warsaw says it sees Wagner’s presence in Belarus as a potential threat and is seeking to shore up its eastern flank.
Belarusian leader Alexander Lukashenko has previously denied provoking a migrant crisis in Europe by luring would-be migrants to its borders with EU nations.
