Russia and Ukraine discussed further prisoner swaps on Wednesday at a brief session of peace talks in Istanbul, but the sides remained far apart on ceasefire terms and a possible meeting of their leaders.

Russian and Ukrainian negotiating teams will again meet in Istanbul, Turkey, on Wednesday, Ukrainian President Volodymyr Zelenskyy confirmed, for the first such meeting since President Donald Trump set a 50-day deadline for a ceasefire to be reached.

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.
