Ukrainian President Volodymyr Zelenskiy on Tuesday said he was prepared to negotiate with Russia "in any format" once a ceasefire takes hold while the Financial Times reported that Russian President Vladimir Putin has offered to halt Moscow's invasion at the current frontlines.

Authorities in Ukraine say Russian drones have battered the Ukrainian port city of Odesa in a nighttime attack.

Moscow launched strikes across Ukrainian cities hours after Putin said he was considering a pause on civilian targets.
