"This is an initiative of the American side and personally of the president of the United States. We can regard it as an opportunity rather than an agreement. Whether it will work or not, and what exactly will work, I cannot say at this point. There is no official agreement on a ceasefire, as is typically reached during negotiations," Zelenskyy told reporters Thursday evening. Zelenskyy argued the Russians had not accepted such a deal last year and he sounded skeptical about their sincerity this time.
