Russia declared a unilateral ceasefire with Ukraine from May 8 to May 9, 2026, coinciding with its World War II Victory Day observances, and warned of a "massive missile strike" on Kyiv if the truce was breached. The announcement, made on May 4, framed the pause in hostilities as a gesture tied to the national holiday.

Ukraine responded by declaring its own ceasefire from May 5 to May 6, 2026, stating it was "not serious" to expect Kyiv to observe a truce during a Russian military commemoration. Ukrainian officials dismissed Moscow's move as a symbolic gesture lacking credibility amid ongoing attacks.

The conflicting truce periods underscore the absence of mutual trust or coordination between the two sides. No international mediation efforts or verification mechanisms were announced, and fighting continued elsewhere along the front lines. Military operations are expected to resume fully after each declared ceasefire window.
