May 30 (UPI) -- Ukraine said it will not send a delegation for peace talks to Istanbul Monday until Russia provides details of its cease-fire proposal.

Ukraine accused Russia, which has said it will send a delegation to Istanbul for the talks, of stalling in peace negotiations.

"Russia is dragging out the war and doing everything to simply deceive countries that are still trying to influence Moscow with words, not pressure. Words with Moscow do not work. Even the so-called "memorandum" that they promised and supposedly prepared for more than a week has not yet been seen by anyone," Ukrainian President Volodymyr Zelensky said in a video posted to the presidential website.
