Polish Prime Minister Donald Tusk told a press conference that "all indications" point to a Russian Kh-101 cruise missile, stating it was most likely Russian and carried a warhead . Poland's Deputy Defense Minister Cezary Tomczyk confirmed "with full responsibility" that the weapon was a Russian cruise missile capable of carrying a nuclear warhead . Ukrainian Foreign Minister Andrii Sybiha called the incident a "horrific reality" and confirmed a Russian cruise missile had entered NATO airspace, urging allies to strengthen air defenses .
Both sides treated the origin as clear — unlike the November 2022 Przewodów incident, when a Ukrainian air-defense missile struck a Polish village, causing a diplomatic firestorm over attribution. In this case, Polish and Ukrainian officials immediately and unequivocally identified the weapon as Russian, with no ambiguity about responsibility .
Tusk described the crash as a "tough night" for Polish air defense and said the government would quickly evaluate transferring additional Patriot air defense interceptor missiles to Ukraine, framing the decision as a matter of Polish national security: strengthening Ukraine's air defenses helps protect Polish territory from stray Russian missiles . This came after Poland had already transferred five PAC-3 MSE Patriot interceptor missiles to Ukraine in early July 2026 at the request of NATO and the U.S. .
Ukraine offered and dispatched a Ukrainian missile expert to Poland to assist Polish investigators in identifying the missile type and analyzing the crash circumstances . As of reporting on July 30, that expert had traveled to Poland and was participating in the investigation .
The missile crash occurred just one day after Tusk and Ukrainian President Volodymyr Zelenskyy met in Lublin on July 29 to discuss defense cooperation, Zelenskyy's recent Washington visit, and bilateral issues including historical dialogue and Ukrainian refugees in Poland . The crash directly underscored the threat the two leaders had discussed — stray Russian missiles hitting Polish territory — and gave immediate practical urgency to Tusk's subsequent pledge to review additional Patriot transfers as a national-security measure .
