Poland said Thursday it had convened an emergency U.N. Security Council meeting after accusing Russia of violating its airspace with a drone raid the previous day.

Warsaw said the incident was not accidental and branded it an "unprecedented" attack on Poland, NATO and the European Union, but Moscow denied targeting the country and said there was no evidence the drones were Russian.

Stray Russian drones and missiles have entered the airspace of NATO members, including Poland, several times since Moscow launched its invasion of Ukraine in 2022, but no NATO country has ever attempted to shoot them down.

The incident was "an attempt to test the mechanism of action within NATO and our readiness to respond," Polish President Karol Nawrocki said Thursday during a visit to an airbase in western Poland.

The UN Security Council will hold an emergency meeting to discuss "the violation of Polish airspace by Russia", the Polish foreign ministry said without specifying a date.
