The Pentagon said Tuesday it could not corroborate media reports that two Russian missiles landed in NATO member Poland, but added it was investigating the allegations.
Pentagon spokesman Pat Ryder said: “We are aware of reports claiming that two Russian missiles hit locations within the Polish or Ukrainian borders.”
“At this time, we have no information to corroborate that there was a missile attack,” Ryder told reporters, adding that the Pentagon was “further investigating this.”
Poland, which borders Ukraine, which Russian President Vladimir Putin invaded on February 24, has welcomed thousands of Ukrainian refugees displaced by fighting.
Moscow hit a Ukrainian city with missiles on Tuesday, plunging seven million homes into darkness and dampening its jubilation over the humiliating Russian withdrawal from the city of Kherson.
It was not clear if the missiles that may have hit Poland were part of the same wave.
About 10,000 US personnel are in rotation in Poland and regularly contribute to NATO missions, according to official government sources.
Ryder said protecting these units would be taken “very seriously”.
“I am very confident in any military protection measures we take, whether in Poland or elsewhere,” he said.
“But again, I’m not going to get ahead of myself here. I’m going to get the facts. And when I have more to offer, I will.”
