Poland’s president has said the missile which stuck his country was probably a Russian-made S-300 dating from the Soviet era.
Ukraine, once part of the Soviet Union, fields Soviet- and Russian-made weaponry.
Before the Polish and NATO assessments, U.S. President Joe Biden had said it was “unlikely” that Russia fired the missile but added: “I’m going to make sure we find out exactly what happened.”
A Russian Defense Ministry spokesman in Moscow said no Russian strike Tuesday was closer than 35 kilometers (22 miles) from the Ukraine-Poland border.
The Kremlin denounced Poland’s and other countries’ initial response and, in rare praise for a U.S. leader, hailed Biden’s “restrained, much more professional reaction.”
“We have witnessed another hysterical, frenzied, Russo-phobic reaction that was not based on any real data,” Kremlin spokesman Dmitry Peskov said.
Later Wednesday, Russia’s Foreign Ministry summoned the Polish ambassador in Moscow; the discussion reportedly lasted about 20 minutes.
Russia’s assault on power generation and transmission facilities Tuesday included Ukraine’s western region bordering Poland. Ukraine’s military said 77 of the more than 90 missiles fired were brought down by air defenses, along with 11 drones.
The countrywide bombardment by barrages of cruise missiles and exploding drones clouded the initial picture of what happened in Poland.
“It was a huge blast, the sound was terrifying.” said Ewa Byra, the primary school director in the eastern village of Przewodow, where the missile struck. She said she knew both men who were killed — one was the husband of a school employee, the other the father of a former pupil.
Another resident, 24-year-old Kinga Kancir, said the men worked at a grain-drying facility.
“It is very hard to accept,” she said. “Nothing was going on and, all of a sudden, there is a world sensation.”
In Europe, NATO members called for a thorough investigation and criticized Moscow.
“This wouldn’t have happened without the Russian war against Ukraine, without the missiles that are now being fired at Ukrainian infrastructure intensively and on a large scale,” said German Chancellor Olaf Scholz.
Swaths of Ukraine were without power after the aerial assault. Zelenskyy said about 10 million people lost electricity, but tweeted overnight that 8 million were subsequently reconnected. Previous strikes had already destroyed an estimated 40% of the country’s energy infrastructure.
Ukraine said the bombardment was the largest on its power grid so far.
