Ukrainian President Volodymyr Zelenskyy reported that Russia launched a huge assault overnight using almost 300 attack drones and 25 missiles. The strikes targeted Ukraine's energy infrastructure, worsening the existing electricity and heating outages amid a harsh winter. The attacks caused widespread damage to homes and civilian buildings in Kyiv, Dnipro, Kharkiv, and Donetsk. Zelenskyy said "several hundred thousand households" in Kyiv region remain without electricity, with temperatures falling as low as -12 degrees Celsius. He emphasized, "wherever Russia tries to destroy, Ukrainians support one another, and internal resilience is what is most needed right now." He also condemned a missile strike on a postal terminal in Korotych, Kharkiv region, which killed four people. Zelenskyy stated, "Every such strike against life is a reminder that support for Ukraine cannot be stopped. Missiles for air defense systems are needed every day, and especially during winter." The President called on the world to respond with new aid packages. "We expect the acceleration of deliveries already agreed with America and Europe. Russia must come to learn that cold will not help it win the war. Thank you to everyone who is helping."
