Diplomats from the UK, France, Germany, Ukraine and the US will hold fresh talks in London on Wednesday aimed at securing a ceasefire in the three-year war between Ukraine and Russia. The talks come amid growing speculation that Russia might be willing to halt its invasion along current front lines in return for significant concessions.

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

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.
