Negotiators for the warring sides in Istanbul appeared to make little progress on ceasefire terms or a possible summit between their presidents – with their meeting ending after less than an hour.

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. A Russian delegation led by presidential aide Vladimir Medinsky left Moscow on Wednesday for the talks in Turkey with a Ukrainian team led by Security and Defense Council Secretary Rustem Umerov.
