KYIV, Ukraine (AP) — Russia has attacked electrical power facilities in much of Ukraine, including the country’s largest hydroelectric plant, causing widespread outages and killing at least three people. Ukraine’s energy minister says the nighttime drone and rocket attacks were the largest on the country’s energy sector in recent times. He says the goal was to cause a large-scale disruption of the energy system. The attacks caused a fire at the Dnipro Hydroelectric Station, which supplies electricity to the Zaporizhzhia Nuclear Power Plant, Europe’s largest nuclear power installation. The International Atomic Energy Agency says the main 750-kilovolt power line to the plant was cut off but a lower-power backup line was working.
