Speaking ahead of an emergency meeting, Tusk said it was the first time Russian drones had been shot down over Poland.
A military operation has ended after Polish and NATO aircraft were deployed and most airports have reopened. Russia has yet to comment.
The drones that entered Poland were part of the latest major aerial attack on Ukraine, where Russia launched 415 drones overnight.
Ukraine’s President Zelensky says at least eight strike drones were aimed toward Poland, calling the escalation an extremely dangerous precedent for Europe.
