The United States had no warning about the alleged drone attack on the Kremlin that Russia claimed was an assassination attempt on Russian President Vladimir Putin, which Ukraine vehemently denies, according to a US official, APA reports citing CNN.
"Whatever happened, there was no advanced warning," the US official told CNN, adding that authorities are still trying to figure out what exactly happened.
Another US official told CNN they are still working to assess Russia's claims and have not yet validated the Kremlin assertion that Ukraine tried to assassinate Putin.
