In July 2026, the Belarusian foreign ministry alerted Polish authorities to a suspected terrorist plot on Polish soil. The warning, delivered to Poland’s chargé d’affaires in Minsk, alleged that a person residing in Poland—whose residence permit was recently revoked by Polish officials—was planning an attack. The reported target was the underage children of a Belarusian activist living in Poland, with the motive cited as revenge regarding the suspect’s legal status.

Polish Foreign Minister Radosław Sikorski confirmed that the warning was being treated seriously, stating, “We take every warning about terrorism seriously and verify it.” Polish security services initiated a review of the intelligence provided by Belarus.
