Putin's spokesman Dmitry Peskov, without providing evidence, said Ukraine had acted on U.S. orders with the alleged drone attack on the Kremlin citadel in the early hours of Wednesday.
"Attempts to disown this (attack on the Kremlin), both in Kyiv and in Washington, are, of course, absolutely ridiculous.
Separately, Russia's foreign ministry said the alleged drone attack "must not go unanswered" and that it showed Kyiv had no desire to end the 15-month old war at the negotiating table.
Russian emergency services quickly extinguished a fire at the Ilsky oil refinery, one of the largest in southern Russia, after a drone attack set product storage facilities ablaze, TASS news agency reported.
