Russia's Defense Ministry has declared a unilateral ceasefire in Ukraine to mark Victory Day, commemorating the defeat of Nazi Germany in World War II. The ceasefire is set for Friday and Saturday. The ministry warns of a massive missile strike on Kyiv if Ukrainian forces disrupt the celebrations. This announcement comes as Ukraine has been launching drone attacks deep inside Russia. The traditional military parade in Moscow will be pared down due to security concerns. Victory Day has been a key pillar of President Vladimir Putin's tenure, showcasing military might and patriotic pride.
