Poland said Wednesday that a Russian-made missile fell in the country’s east, killing two people, though U.S. President Joe Biden said it was "unlikely” it was fired from Russia.
The blast, which Ukrainian President Volodymr Zelenskyy decried as "a very significant escalation,” prompted Biden to call an emergency meeting of G-7 and NATO leaders. A deliberate, hostile attack on NATO member Poland could trigger a collective military response by the alliance.
But key questions around the circumstances of the missile launch — none larger than who fired it — remained amid the confusion caused by a blistering series of Russian airstrikes across the nearby border in Ukraine. Russia denied any involvement in the Poland blast.
Three U.S. officials said preliminary assessments suggested the missile was fired by Ukrainian forces at an incoming Russian one amid the crushing salvo against Ukraine’s electrical infrastructure Tuesday. The officials spoke on condition of anonymity because they were not authorized to discuss the matter publicly.
That assessment and Biden’s comments at the Group of 20 summit in Indonesia contradict information earlier Tuesday from a senior U.S. intelligence official who told the AP that Russian missiles crossed into Poland.
The Polish government said it was investigating and raising its level of military preparedness. Biden pledged support for Poland’s investigation.
A statement from the Polish Foreign Ministry identified the weapon as being made in Russia. President Andrzej Duda was more cautious, saying that it was "most probably” Russian-made but that its origins were still being verified.
"We are acting with calm,” Duda said. "This is a difficult situation.”
Ukraine still maintains stocks of former Soviet and Russian-made weaponry, including the S-300 air-defense missile system.
Biden’s decision to convene the emergency meeting upended schedules for the final day of the Group of 20 summit in Indonesia.
European Commission President Ursula von Der Leyen said participants discussed the blast in Poland and expressed their continued solidarity with Ukraine.
"We offer our full support to Poland and assistance with the ongoing investigation. We will remain in close contacts with our partners on the next steps. We will stand with Ukraine as long as it takes,” she said.
Biden, who was awakened overnight by staff with the news of the missile while attending the summit, called Duda to express his condolences. On Twitter, Biden promised "full U.S support for and assistance with Poland’s investigation,” and "reaffirmed the United States’ ironclad commitment to NATO.”
NATO Secretary-General Jens Stoltenberg called the meeting of the alliance’s envoys in Brussels. The U.N. Security Council also planned to meet Wednesday for a previously scheduled briefing on the situation in Ukraine.
Poland’s statement did not address whether the strike could have been a targeting error or if the missile could have been knocked off course by Ukrainian defenses.
Poland and NATO used language that suggested they were not treating the missile blast as an intentional Russian attack, at least for now. A NATO statement called it a "tragic incident.”
If Russia had deliberately targeted Poland, it would risk drawing the 30-nation alliance into the conflict at a time when it is already struggling to fend off Ukrainian forces.
Polish media reported that the strike took place in an area where grain was drying in Przewodów, a village near the border with Ukraine.
Underscoring the extraordinarily tense situation, CIA Director William Burns was in Kyiv on Tuesday during the barrage of Russian missiles that struck dozens of targets in the country. He remained in the U.S. Embassy in Kyiv during the strikes.
Burns briefed Zelenskyy and Ukrainian officials on his meeting in Turkey with the head of Russia’s foreign intelligence service, according to another U.S. official who spoke on condition of anonymity to discuss intelligence matters.
Burns told Ukrainian officials that he had delivered a U.S. warning to Russia not to use nuclear weapons, the U.S. official said.The Russian Defense Ministry denied being behind "any strikes on targets near the Ukrainian-Polish border” and said in a statement that photos of purported damage "have nothing to do” with Russian weapons.
Polish Foreign Minister Zbigniew Rau summoned the Russian ambassador and "demanded immediate detailed explanations,” the government said.
The strike came to light as Russia pounded Ukraine’s energy facilities with its biggest barrage of missiles yet, striking targets across the country and causing widespread blackouts.
The barrage also affected neighboring Moldova. It reported massive power outages after the strikes knocked out a key power line that supplies the small nation, an official said.
The missile strikes plunged much of Ukraine into darkness and drew defiance from Zelenskyy, who shook his fist and declared: "We will survive everything.”
In his nightly address, the Ukrainian leader said the strike in Poland offered proof that "terror is not limited by our state borders.”
