During talks that lasted just 40 minutes, Ukraine proposed a Putin-Zelenskyy meeting in August

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.

“We have progress on the humanitarian track, with no progress on a cessation of hostilities,” Ukraine’s chief delegate, Rustem Umerov, said after talks that lasted just 40 minutes.
