President Donald Trump issued a brief statement about the suddenly tense standoff between Poland and Russia.
Polish Prime Minister Donald Tusk warned the NATO member's parliament that Russia had crossed a line by sending drones into its airspace during an early Wednesday attack against Ukraine, saying "this situation brings us the closest we have been to open conflict since World War II," and the U.S. president briefly commented on social media.
"What’s with Russia violating Poland’s airspace with drones?" Trump posted on Truth Social at 11:09a.m. EST. "Here we go!"
European leaders condemned the incident as an escalation by the Kremlin, which has continued its attacks on Ukraine despite Trump's efforts to push Russian President Vladimir Putin and Ukraine President Volodymyr Zelenskyy into peace talks.
Polish military officials called the incursion “act of aggression" and said all of the drones were shot down with help from NATO allies, and Tusk said he has activated Article 4 of NATO’s treaty, which allows member nations to demand consultations with their allies.
That's only the eighth time since NATO was established in 1949 that Article 4, which does not trigger a military reaction, has been invoked by a member.
