KYIV, Ukraine — Poland's president said Wednesday that it appears a missile that landed just inside the country's border was from Ukraine in what he called an "unfortunate accident."
"We have no evidence at the moment that it was a rocket launched by Russian forces," President Andrzej Duda said. "However, there are many indications that it was a missile that was used by Ukraine's anti-missile defense."
Two Polish citizens were killed Tuesday when the missile came crashing down in a rural village in eastern Poland, just a few miles from the western border of Ukraine. This happened amid a Russian barrage of missiles fired at cities across Ukraine, with Ukraine responding with its air defense systems.
NATO members discussed the issue in Brussels, and the secretary general of alliance, Jens Stoltenberg, said a preliminary analysis pointed to a Ukrainian air defense missile that had been fired at an incoming Russian missile.
"Let me be clear: this is not Ukraine's fault. Russia bears ultimate responsibility as it continues its illegal war against Ukraine," Stoltenberg said.
In Russia, Defense Ministry spokesman Igor Konashenkov said Russian specialists had studied images of the explosion in Poland and concluded rocket fragments were from an S-300 surface-to-air missile system fired by Ukraine.
Konashenkov insisted Russia carried out a wave of what he called "precision" strikes on Ukrainian military and energy infrastructure. He said this included attacks in western Ukraine, but all were 20 miles or more away from Poland's border.
At the G20 summit in Indonesia, President Biden has said the missile was "probably" not fired from Russia. Still, he supported an investigation with Poland and condemned Moscow's latest attacks on Ukraine.
In Ukraine, President Volodomyr Zelenskyy spoke in a brief video on Wednesday morning, wishing citizens a "normal day" after Tuesday's missile barrage. He didn't say whose missile may have exploded in Poland.
This was in contrast to his initial comment Tuesday night, when he said, "This is a Russian missile attack on collective security."
One of his top advisers, Mykhailo Podolyak, said that regardless of whose missile landed in Poland, Russia was responsible.

"Only Russia is responsible for the war in Ukraine and massive missile strikes," he tweeted. "Only Russia is behind the rapidly growing risks for the border countries. No need to look for excuses and postpone key decisions. Time for Europe to close the sky over Ukraine."
Tuesday afternoon's missiles targeted the Ukraine's electricity grid as it's been doing for the past month.
Ukraine says it shot down about 70 of the incoming missiles, in line with other recent attacks.
But Ukraine's energy systems, which already include daily power outages in many parts of the country, suffered another heavy blow.
In the capital Kyiv, the largest city with around 3 million residents, about half the homes and businesses were without power, according to Mayor Vitali Klitschko. Other large cities were in similar condition, if not worse.
One woman was killed in Kyiv when a missile slammed into her apartment in a residential area near the center of the city. There were no obvious military, government or energy facilities in the area.
It was not clear why the building would have been targeted, or if perhaps a Ukrainian air defense system hit a Russian missile, with the remnants of that Russian missile hitting the building.
Standing in the darkness outside the apartment building, Vladimir Yanachuk said he expected many more Russian attacks, but this was not weakening the resolve of Ukrainians.
"We are not afraid about this. Ukrainians are not afraid about this," he said. "Winter will be hard. But this winter will be hard not only for Ukrainians, but for Russian soldiers too."
As he was speaking in the street, the lights suddenly came back on in surrounding apartment buildings, though not the one that had been hit.
Ukrainians have been rapidly repairing the power outages inflicted by the Russians, but the sheer number of attacks has strained the country's capacity to keep up.
Russia has damaged around 40% of the country's electricity system, according to Ukrainian officials.
