ISTANBUL (Reuters) -Vladimir Medinsky, the head of Russia's delegation at Ukraine peace talks in Istanbul, said on Friday after the negotiations that Moscow was satisfied with the results and was ready to keep talking to Kyiv.

After dangling the possibility of his attendance, Trump says he will stay away but still wants to meet with Putin, further weakening the Istanbul talks.

Ukraine will make securing a ceasefire a priority in expected talks with a Russian delegation in Istanbul on Friday, a Ukrainian diplomatic source said, adding there was also a need for "confidence-building measures".
