Ukrainian experts will join the international joint investigative commission at the site in Poland where a rocket landed on Tuesday, killing two people, President Volodymyr Zelenskyi said, CNN reports.

“Yesterday (Wednesday) we insisted that we be included in the international joint investigative commission, and already late in the evening we received confirmation. In the morning, our specialists will go there and join this community of professionals,” Zelenskyy said during a speech at the Bloomberg Forum for the new economy.

“I don’t know what happened. We don’t know for sure. The world doesn’t know. But I’m sure it was a Russian missile, I’m sure we fired from air defense systems,” Zelenskyy said. .

Only after the investigation will it be possible to draw conclusions as to which missile fell on the territory of Poland, he said.

Separately, a source in the president’s office confirmed to CNN that the Ukrainian group is being sent to the crash site in Poland, where Polish and American investigators are working.

“Today there is a lot of evidence that one of the missiles that was supposed to shoot down the Russian missile did not hit the target, the self-destruct system did not work, and this missile, unfortunately, led to the tragedy,” he said. Jakub Kumoh, head of the International Policy Department of the Office of the President of Poland Andrzej Duda.

Polish Prime Minister Mateusz Morawiecki said that the explosion on Tuesday evening in a Polish town on the border with Ukraine was caused by a Russian missile shot down on Polish territory “without any intention on either side.”

While no one is accusing Ukraine of defending itself, Ukrainian President Volodymyr Zelenskyi said on Wednesday that he had no doubt that an explosion in Poland that killed two people was not caused by a Ukrainian missile, Reuters reported.

“I have no doubt that it was not our missile,” Ukrainian media quoted him as saying.

However, according to him, it is possible that the incident, when a rocket hit a village in the south-east of Poland, was the result of a provocation by Russia, the Polish Prime Minister said on Wednesday.

“We cannot rule out that the bombing of Ukrainian infrastructure near the border was a deliberate provocation carried out in the hope that such a situation might arise,” Mateusz Morawiecki said in the Polish parliament.
