"Just now I spoke with US President Donald Trump about the multiple violations of Polish airspace by Russian drones overnight," Nawrocki wrote on X.
"The conversation was part of a series of consultations I have been conducting with our allies," he said, adding that the talks "confirmed allied unity."
The head of Nawrocki's office, Zbigniew Bogucki, told broadcaster Polsat News that it was the fourth such exchange between the two leaders, following group teleconferences before and after Trump’s recent meeting with Russian President Vladimir Putin in Alaska, and after Nawrocki’s visit to the United States last week.
Before the call, Trump wrote on Truth Social: "What’s with Russia violating Poland’s airspace with drones? Here we go!"
Poland’s military said Russian drones breached its airspace 19 times during an overnight attack on Ukraine, with some entering from Belarus, with no casualties reported.
The incident marked the first time Russian drones had been shot down over NATO territory, Polish state news agency PAP reported.
Prime Minister Donald Tusk said he received not only messages of solidarity but also offers of concrete air defence support from allies including France, Germany and NATO Secretary-General Mark Rutte.
The breaches, described by Polish officials as an "act of aggression" and "unprecedented," triggered consultations under Article 4 of the NATO treaty and a formal protest note delivered to Russia’s chargé d’affaires in Warsaw.
Foreign Minister Radosław Sikorski called the incident an "unprecedented attack" not only on Poland, but also on NATO and the European Union.
On Wednesday morning, Nawrocki discussed the incident with Tusk, defence officials and top military commanders at an emergency meeting of the National Security Bureau (BBN).
"What happened last night is a moment without precedent in NATO’s history, as well as in Poland’s recent history," the president told reporters.
He thanked Polish pilots, soldiers and NATO allies for their role in shooting down drones that posed a direct danger.
“We proved that within the alliance we can respond to such situations effectively,” he said, adding that Poland must strengthen its counter-drone defences in close cooperation with NATO.
On Thursday, Nawrocki is set to host a meeting of the National Security Council attended by political leaders and parliamentary group heads to review the incident and consider measures to prevent similar events in the future.
The National Security Council serves as an advisory body to the president and includes senior officials such as the Speakers of both houses of parliament, the prime minister, the defence, interior and foreign ministers, and other prominent politicians from both the government and opposition.
