ISTANBUL − Russia's Vladimir Putin spurned a challenge to meet face-to-face with Volodymyr Zelenskyy in Turkey, instead sending a second-tier delegation to planned peace talks, while Ukraine's president said his defence minister would head up Kyiv's team.

Russia and Ukraine are set to hold their first direct peace talks in three years, both countries said Thursday, but hopes for a breakthrough remained dim after Russian President Vladimir Putin spurned an offer by Ukrainian President Volodymyr Zelenskyy to meet face-to-face in Turkey.

U.S. Secretary of State Marco Rubio said on Thursday the only way a breakthrough will happen in the efforts to end Russia's war in Ukraine would be through direct talks between President Donald Trump and Russian President Vladimir Putin,
