Russia and Ukraine to 'immediately' start ceasefire talks, says TrumpPutin said he was ready to work with Ukraine on a "memorandum on a possible future peace agreement", while Zelensky said "this is a defining moment", and urged the US not to distance itself from talks. Despite the note of optimism from Trump, who also spoke with Ukrainian President Volodymyr Zelensky, any ceasefire or peace deal does not appear close. US President Donald Trump says Russia and Ukraine will "immediately" start negotiating towards a ceasefire and an end to the war, after a two-hour phone call with Russian counterpart Vladimir Putin. After his one-on-one call with Trump, Zelensky reaffirmed Ukraine's desire for a "full and unconditional ceasefire", and warned if Moscow is not ready, "there must be stronger sanctions". This, he added would define "a number of positions" including "principles of the settlement and a timeline for concluding a possible peace agreement...including a possible ceasefire for a certain period of time, should relevant agreements be reached".
