Russia and Ukraine exchanged large waves of attack drones overnight into Sunday as the two combatants maneuvered ahead of Friday's planned summit in Alaska between U.S. President Donald Trump and Russian President Vladimir Putin.

The White House says Trump is open to Ukraine joining talks with Putin on Friday, as Zelensky insists any deal without Kyiv is a “dead decision”.

The White House has said Donald Trump is "considering" inviting Volodymyr Zelenskyy to his meeting with Vladimir Putin - with European leaders saying the "only approach" to ending the war must involve Ukraine.
