Ukraine’s President Volodymyr Zelensky raised the stakes ahead of a potential meeting with Vladimir Putin in Turkey on Thursday by saying he wouldn’t hold talks with any Russian representative other than the president himself.

Putin hasn't yet said whether he will be at the talks, which Trump has urged Ukraine and Russia to attend as part of Washington's efforts to stop the fighting.

President Volodymyr Zelensky said he will meet with Turkish President Recep Tayyip Erdogan in Ankara, but said both leaders are ready to fly to Istanbul if Russian President Vladimir Putin chooses to attend the talks there.
