Polish Foreign Minister Radosław Sikorski revealed at the Munich Security Conference on Saturday that French President Emmanuel Macron is hosting European leaders for an emergency meeting in Paris that's scheduled for Monday.

Macron hasn't yet confirmed the meeting officially and the guest list is currently unknown.

Sikorski said he was "very glad" Macron is convening the meeting, emphasizing that the leaders will "in a very serious fashion" address the challenges European nations face during President Donald Trump's second term.

"President Trump has a method of operating which the Russians call razvedka boyem —reconnaissance through battle: You push and you see what happens, and then you change your position," he said, according to Politico. "And we need to respond," the Polish minister said at the Munich conference."
