Normunds Mežviets said Belarusian tactics were becoming more aggressive and alleged that migrants were being prepared in special camps before being sent toward countries such as Poland, adding that Minsk had developed infrastructure near the border, including depots and temporary lodging, to support the effort. The comments are likely to deepen concerns in Poland and the Baltic states, which have long accused Minsk and Moscow of using migration as a pressure tactic against the EU. The allegations about combat training and staging facilities were made by Latvia’s security service and were not independently verified in the report.
