Jan 24 (Reuters) - Russia launched another vast attack on Ukraine's energy system, rocking Kyiv with explosions overnight and into Saturday morning, leaving 1.2 million properties without power countrywide during sub-zero winter cold.
Deputy Prime Minister Oleksiy Kuleba said more than 3,200 buildings in the capital remained without heating in the late evening, down from 6,000 in the morning. Night-time temperatures were hovering around -10 degrees Celsius (14 F).
