KYIV, Ukraine (AP) — Russian President Vladimir Putin on Monday declared a unilateral 72-hour ceasefire next week in Ukraine to mark Victory Day in World War II as the U.S. presses for a deal to end the 3-year-old war. Kyiv insisted on a longer and immediate truce.

The ceasefire would begin May 8 and end on May 10, and the Kremlin said it expects Ukraine to adhere to it as well. Ukraine has been pushing for a full truce.
