The U.S. Central Intelligence Agency (CIA) has determined that Ukraine did not attack Russian President Vladimir Putin or one of his residences, U.S. media have reported.

Various media, including the Wall Street Journal as well as the broadcasters PBS and CNN cited unnamed U.S. government officials in their reports published on Wednesday evening contradicting serious accusations made by Moscow at the start of the week.

Initially, U.S. President Donald Trump also criticized Ukraine for the alleged attack after a conversation with Putin.

Kiev has vehemently denied attacking one of Putin's residences, saying instead it was a Russian pretext to continue the war against Ukraine despite ongoing peace negotiations and to once again target government buildings in Kiev with missiles.

On Wednesday, Russia presented possible evidence of the attack for the first time, including remnants of a purportedly Ukrainian drone. Many experts doubt that the attack described by Russia took place as claimed.
