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.

Marco Rubio says the "only way we’re going to have a breakthrough here is between President Trump and President Putin".
