Poland says the UN Security Council will convene an emergency meeting regarding the alleged violation of the country's airspace by Russia.

Poland's foreign ministry announced on social media on Thursday that the meeting would be held at the country's request. The session will begin at 3 p.m. on Friday.

Polish Prime Minister Donald Tusk told parliament on Wednesday that there had been 19 drone intrusions into his country's airspace overnight.

A US think tank, the Institute for the Study of War, released an analysis on Wednesday, saying the incursion into Polish airspace "of at least 19 drones in a single night is notable."

The institute said, "It is unlikely that such a number of drones could have all entered into Polish airspace by accident or as a result of a technical or operator error."

It added, "Russia may have been preparing for the September 9-10 incursion for months."

According to the institute, "Russia is likely trying to probe Poland's and NATO's defensive capabilities and reaction times while observing their command and control structure in action."

It said, "Russia likely also aimed to test the interoperability of NATO member states working to neutralize a threat in NATO airspace."

Ukrainian President Volodymyr Zelenskyy also spoke about the drones at a news conference on Thursday.

He said, "There is a full analysis of the drones' flight paths, and more and more details are being clarified regarding the design" of the aerial vehicles.

He added that all of this indicates that Russia's drone launch into Polish territory through Ukraine and Belarus was "deliberate and definitely not an accident."

Zelenskyy also noted, "Ukraine is offering all European neighbors -- our own neighbors and Russia's neighbors -- a joint program for financing, producing, and developing interceptor drones."
