The United States has reportedly delivered repeated intelligence warnings to Poland that Russia could carry out military provocations in the coming months, with possible scenarios ranging from attacks inside Polish territory to increased troop deployments near NATO’s eastern frontier.

According to a report by the Polish news outlet ONET, American officials briefed Warsaw on several potential threats. Among the possibilities discussed were a limited ground incursion into Poland, airstrikes against locations within the country, and the positioning of Russian or Belarusian military forces along NATO’s eastern flank.

Officials in Poland’s presidential office told ONET that Washington has issued multiple warnings about what it believes could be a Russian plan involving Poland. Polish intelligence sources reportedly outlined additional possibilities as well, including drone strikes targeting key infrastructure and “simulated airstrikes” intended to force Poland to activate its air defense network.

Polish Prime Minister Donald Tusk acknowledged the heightened security concerns, saying his government is actively preparing for a variety of potential developments.

“We are preparing intensively for different scenarios,” Tusk said. “I don’t intend to scare anyone, but the coming months, also due to the changing nature of the war in Ukraine, may truly be critical, especially for the Baltic states. These concerns are real. We must not underestimate them.”

Poland’s Foreign Minister Radosław Sikorski also directed a pointed warning at the Kremlin, urging Russia not to challenge the NATO alliance. “It would be a serious act of reckless folly if Vladimir Putin decides to test NATO’s unity through a disproportionate action. We know what you are planning. Don’t do it.”

Neither the U.S. government nor Polish authorities have officially verified the reported intelligence assessments. Russia, meanwhile, has not publicly responded to the allegations.
