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 had initially called for direct talks in Turkey's second city "without pre-conditions", before Zelensky announced that he would go in person and expected the Russian president to travel as well. The US is also expected to send a high-level delegation.

WASHINGTON/RIYADH/ANTALYA (Reuters) - U.S. President Donald Trump's senior envoys Steve Witkoff and Keith Kellogg will travel to Istanbul for potential talks on Thursday on how to end Russia's war in Ukraine, three sources familiar with the plans said on Tuesday.
