Russia and Ukraine are due to hold their first direct peace talks in three years Friday. They are expected to gather in Istanbul for Turkish-brokered negotiations but officials and observers expect them to yield little immediate progress on stopping the more than 3-year war. A Ukrainian delegation led by the defense minister was due to meet Friday with a low-level Russian team headed by a presidential aide. The latest push to end the fighting got off to a rocky start on Thursday, when Russian President Vladimir Putin spurned an offer by Ukrainian leader Volodymyr Zelenskyy to meet face-to-face. Delegations from the two countries also flew to different Turkish cities and put together teams of significantly different diplomatic heft for possible talks.
