 Russia accused Ukraine on Wednesday of attacking the Kremlin with drones overnight in a failed bid to kill President Vladimir Putin. There was no immediate comment from Ukrainian authorities on the statement from Moscow. The Kremlin said two drones had been used in the alleged attack on Putin's residence in the Wald Kremlin citadel, but had been disabled by electronic defenses. It said Russia reserved the right to retaliate a comment that suggested that Moscow might use the alleged incident to justify a further escalation in its war with Ukraine. We regard these actions as a planned terrorist act and an attempt on the president's life, carried out on the eve of Victory Day, the May 9 parade, at which the presence of foreign guests is also planned. The statement from the presidential administration said there were no casualties or material damage. RIA news agency said Putin had not been in the Kremlin at the time and was working on Wednesday at his Novo-Ulgariyovo residence outside Moscow.
