BREAKING: Biden official claims US had no warning of Ukraine's alleged assassination attempt on Putin

Following an alleged assassination attempt on Russian President Vladimir Putin by Ukraine overnight, Biden administration officials are saying they had no warning of the drone attack on the Kremlin ahead of time. 

Secretary of State Antony Blinken told the Washington Post’s David Ignatius on Wednesday that he was taking comments from the Kremlin with a "large shaker of salt," according to Politico. 

The Kremlin has accused Ukraine of carrying out the attack, though Kyiv has denied these allegations. Officials instead say the attack was a pretext created by the Kremlin to escalate the ongoing war. 

Two US officials told Politico that senior Biden administration officials are working to confirm who conducted the attack, whether ordered by Kyiv, carried out by a pro-Ukraine group, or a false flag operation by the Kremlin.

If it was Ukraine, "we had no advance knowledge," one of the officials told the outlet who, like others, was granted anonymity. 

"We are looking into the report but aren’t able to confirm it or validate its authenticity," said another.

Alina Polyakova, president and CEO of the Center for European Policy Analysis in Washington, DC, said, "the idea that this was an assassination attempt is absolutely ludicrous. The Kremlin is a bunker and this looked like a makeshift drone that could only cause minimal damage."

Senior adviser to Ukrainian President Volodymyr Zelensky Mykhailo Polodyak, said "Ukraine has nothing to do with drone attacks on the Kremlin," He added that such a strike would only lead to Moscow sending more missiles into Ukraine. "Why would we need this? Where is the logic in that?"
