World leaders react to the missile strike that hit a Polish village

Poland raised its military readiness after what the country's President Andrzej Duda said was "most probably" a strike by a Russian-made missile. However he has since told reporters: "Absolutely nothing indicates that this was an intentional attack on Poland... It's very likely that it was a rocket used in anti-missile defense, meaning it was used by Ukraine's defense forces," he told reporters. 

Here are some of the major reactions from other nations:

U.S President Joe Biden said they would support Poland in figuring out "exactly what happened" and then determine their next steps.

"It is unlikely... that it was fired from Russia. But we'll see," Biden told reporters after the meeting.

Ukrainian President Volodomyr Zelenskyy offered condolences to Duda in a call.

"We exchanged information and are clarifying all the facts," Volodymyr Zelenskyy tweeted.

Foreign Minister Dmytro Kuleba dismissed as a "conspiracy theory" that the missile may have been fired by Ukrainian air defenses.

Russia's defense ministry dismissed reports that missiles fired by Russian forces had landed in Poland.

"Polish mass media and officials commit deliberate provocation to escalate (the) situation with their statement on alleged impact of 'Russian' rockets," it said in an online statement. "Russian firepower has launched no strikes at the area."

German Chancellor Olaf Scholz expressed solidarity with Polish President Andrzej Duda and expressed his condolences.

"Germany stands closely by the side of our NATO partner Poland," Scholz's spokesman tweeted.

UK Prime Minister Rishi Sunak called Duda to express "solidarity" and "offered any assistance needed to urgently establish what happened", Downing Street said.

French President Emmanuel Macron had called for talks at the G20 summit in Indonesia over the strike, his office said before the White House roundtable announcement.

UN chief Antonio Guterres said it was "absolutely essential" to avoid an escalation in the conflict

"The Secretary-General is very concerned by the reports of a missile exploding on Polish territory," according to his spokesman Farhan Haq.
