Low-level delegations from Russia and Ukraine held their first direct peace talks in three years in Istanbul on May 16. The talks, which lasted two hours, brought no significant breakthrough, although both sides agreed to the largest prisoner exchange of the war. It was carried out last weekend and freed 1,000 captives on each side.

KYIV/MOSCOW (Reuters) -Ukraine on Friday resisted pressure from Moscow and Washington to commit itself to attending peace talks with Russia on June 2, saying it first needed to see the proposals Russian negotiators plan to bring to the talks.
