Polish Prime Minister Donald Tusk said on Tuesday that Poland prevented what appeared to be an attempted provocation on its border with the Russian exclave of Kaliningrad overnight.

According to him, “individuals with flashlights” were seen in the area and the border guard told him, just after midnight, of “disturbing movement” on the Polish-Russian border; the guards prevented any incident. Police, the military, border guards and intelligence services reinforced security along the borders with Russia and Belarus, including near Kaliningrad, and counter-terrorism units were sent to the northeast after “more precise” information that acts of sabotage, including a possible incursion by “armed people,” were possible in the first half of November. Tusk said it was not possible to confirm with full certainty that the episode was an attempted provocation and that Russia’s escalation would continue, not limited to that incident. In the Warmian-Masurian region, Polish services intervened near Sępopol, where no one crossed into Polish territory and those observed withdrew into Kaliningrad, according to an RMF24 account carried by United24 Media.
