Russia launched more than 650 drones and more than 50 missiles of various types on Ukraine’s energy infrastructure, bringing power outages and restrictions in all the country’s regions on Thursday, officials said.  The strikes killed at least two people and injured 17, including children between two and 16 years of age, according to authorities, Ukrainian President Volodymyr Zelenskyy said.

Ukrainian cities use centralised public infrastructure to run water, sewage and heating systems, and blackouts stop them from working. Months of attacks have aimed to erode Ukrainian morale as well as disrupt weapons manufacturing and other war-related activity almost four years after Russia’s full-scale invasion of its neighbour.
