Russia's claims that the United States is behind a drone attack on the Kremlin are false, White House national security spokesman John Kirby said on Thursday.

"I can assure you that there was no involvement by the United States in this. Whatever it was did not involve us," Kirby told MSNBC in an interview. "We had nothing to do with this." The United States does not encourage or enable Ukraine to strike outside its borders, he added.

Kirby said it was still unclear what exactly happed at the Kremlin. "We still don't really know what happened" and Washington is still assessing the situation, Kirby said.

Russia earlier on Thursday accused the United States of being behind an attack at Moscow's Kremlin aimed at killing Russian President Vladimir Putin. Russian spokesman Dmitry Peskov "is just lying there," Kirby said.
