Russia renews big attacks on Ukrainian power grid using better intelligence and new tactics

Russia is renewing its strikes on Ukraine's energy system. Ukrainian officials, energy workers and analysts say Moscow is using more missiles and better intelligence to strike the electrical grid across the country. In an unexpected springtime campaign Russia unleashed the most devastating wave of attacks since the early days of the full-scale invasion, plunging tens of thousands of Ukrainians into darkness and leaving Ukrainian officials scrambling to find better ways to defend their energy facilities. The Associated Press was given rare access to two power plants struck in a deadly attack on March 22.
