Zelensky said Ukraine’s government is operating in emergency mode after a major grid accident knocked out two power lines linking Romania, Moldova, and Ukraine, triggering serious outages in Kyiv and central regions including Vinnytsia, Chernihiv, Kharkiv, and Sumy. Current indications point to weather‑related freezing and automatic shutdowns rather than a confirmed cyberattack, and repair crews and energy companies across the country have been mobilized to stabilize the grid and restore heat, electricity, and water supplies.
