The US military is not in a position to independently confirm Ukrainian accounts of atrocities by Russian forces against civilians in the town of Bucha, but has no reason to dispute the accounts either, a senior US defense official said on Monday, Reuters reported.

"We're seeing the same imagery that you are. We have no reason whatsoever to refute the Ukrainian claims about these atrocities -- clearly, deeply, deeply troubling," the official said, speaking on condition of anonymity.

"The Pentagon can't independently and single-handedly confirm that, but we're also not in any position to refute those claims."

The Kremlin has denied accusations related to the murder of civilians in the town.
