Reuters has seen the text of the peace proposals that Ukrainian negotiators plan to present to the Russian side at peace talks scheduled to take place on June 2 in Istanbul.

Ukraine’s foreign minister on Friday accused Russia of stalling peace negotiations, saying that Moscow had yet to share a promised memorandum outlining its peace terms. He said Kyiv wanted to see that document before sending a delegation to a new round of talks Moscow had proposed for Monday in Istanbul.

Ukrainian negotiators at talks scheduled for June 2 in Istanbul will present to the Russian side a proposed roadmap for reaching a lasting peace settlement, according to a copy of the document seen by Reuters.

By making harsh, uncompromising demands in peace talks with Ukraine while continuing to pummel it with waves of missiles and drones, Russian President Vladimir Putin is sending a clear message: He will only accept a settlement on his terms and will keep fighting until they’re met.

A major operation has been launched by Ukraine using drones to destroy Russian bomber planes, according to the Ukrainian security service.

Russia may find itself in a disadvantageous position in the eyes of the United States if it fails to show flexibility in peace negotiations with Ukraine, states Turkish Foreign Minister Hakan Fidan, according to Anadolu.

A Ukrainian security official says a drone attack has destroyed more than 40 Russian planes deep in Russia’s territory.
