Russia claims the United States was behind what it says was a drone attack on the Kremlin that aimed to kill President Vladimir Putin.
It came as Moscow's forces fired more combat drones at Ukrainian cities on Thursday, including the capital, Kyiv, following missile strikes on the city of Kherson on Wednesday which killed 23 people.
Mr Putin's spokesman Dmitry Peskov, without providing evidence, said Ukraine had acted on US orders when it launched what Russia said was a drone attack on the Kremlin building in the early hours of Wednesday morning.
