The US has seen no information so far that contradicts Polish President Andrzej Duda’s “preliminary assessment” that the explosion in Poland yesterday that left two dead “was most likely the result of a Ukrainian defense missile”, - Secretary of Defense Lloyd Austin said at a press conference at the Pentagon, writes CNN.

“Whatever the final conclusions may be, the world knows that Russia bears ultimately responsibility for this incident”, - Austin added.

The US has “full confidence” in the Polish government’s investigation into it, Austin said.

“They’ve been conducting that investigation in a professional and deliberate manner, and so we won’t get ahead of their work. We’re going to stay in close touch with our Polish counterparts as well as with our NATO allies and other valued partners”, - Austin said.

The explosion in Poland and Russia’s continued attacks against civilian infrastructure are “another reminder of the recklessness of Russia’s war of choice”, - Austin concluded.
