The US president will speak to Ukraine's leader in a call on Wednesday, two days before "one-to-one" talks with Putin.

Ukrainian President Volodymyr Zelensky on Wednesday sent a warning to President Trump that Russian President Vladimir Putin is “bluffing” about being open to peace, ahead of a high-stakes summit between the U.

White House Press Secretary Karoline Leavitt said the summit would amount to a 'listening session' for President Trump on the Russian leader's interest in peace.
