Moscow, May 3 (RHC)-- Russia has accused Ukraine of attempting an overnight drone attack on the Kremlin with the aim of killing President Vladimir Putin.  The allegation was made on Wednesday by the Russian government and reported by several state news agencies.

Putin was not injured and there was no material damage to the Kremlin buildings, Russian officials said.

The Kremlin warned that Russia reserves the right to retaliate and that it viewed the alleged assault as a “terrorist” attack.

“The Kremlin has assessed these actions as a planned terrorist act and an assassination attempt on the president on the eve of Victory Day, the May 9 Parade,” state news outlet RIA reported, adding Putin had not changed his schedule and was working as usual.

The president had not been in the Kremlin at the time and was working on Wednesday at his Novo Ogaryovo residence outside Moscow, according to RIA.  Anton Gerashchenko, adviser to the Ukrainian minister of internal affairs, said Russian partisans were likely to have been behind the alleged attack.  “Information appeared that the drone on the Kremlin was launched by Russian partisans from Moscow region,” he wrote on Twitter.

A video circulating on Russian social media, including the channel of the military news outlet Zvezda, showed pale smoke rising behind the main Kremlin Palace in the walled citadel after the purported incident.
