Russian and Ukrainian negotiating teams will again meet in Istanbul, Turkey, on Wednesday, Ukrainian President Volodymyr Zelenskyy confirmed.

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.

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.
