She noted that the US Secretary of Defense held talks with his Polish counterpart.

According to her, the minister made it clear that the American side offered Poland assistance in the investigation.

“But in terms of the alignment and movement of forces and the like, nothing has changed ... in Poland,” TASS quoted Singh as saying.

Earlier, President of Ukraine Volodymyr Zelensky said that Ukraine had nothing to do with the missile falling on the territory of Poland.

He later added, "We don't know 100%."

Joe Biden said that he does not consider Zelensky's words that the rocket that fell on the territory of Poland was not Ukrainian as proof.

As Polish President Andrzej Duda later said, it is highly likely that the fallen missile belonged to the Ukrainian air defense forces.

Secretary of State Anthony Blinken said the US sees no evidence to disprove Poland's findings that the missile was Ukrainian.
