The warring sides are still far apart heading into the third round of U.S.-brokered peace negotiations, set for Wednesday in Istanbul.

Russia and Ukraine are to hold a third round of negotiations in Istanbul, with expectations low for progress on a peace agreement to end the full-scale war that’s in its fourth year.

Ukraine said it would send a high-level negotiating team to Turkey peace talks with Russia, even as Moscow wrote off the talks before they had started.
