Ukraine suspects Russia is not really interested in pausing the conflict and ending the war, and the head of the country’s delegation, Defence Minister Rustem Umerov, said the key points could only be resolved at face-to-face talks between President Zelensky and President Putin.

The covert operation was described as one for the “history books” by Ukraine’s president. According to Ukrainian officials, nearly a third of Moscow’s strategic bomber fleet was destroyed or damaged with cheaply made drones sneaked into Russian territory in the span of a few hours on Sunday.
