ISTANBUL, Turkey (AP) — Russia and Ukraine held their first direct peace talks in three years Friday, gathering in Istanbul for Turkish-brokered negotiations, but officials and observers expected them to yield little immediate progress on stopping the more than three-year war.

Some of Russia's demands include the withdrawal of Ukrainian troops from their own territory as a condition for a ceasefire, an unnamed Ukrainian source told Sky News.
