KYIV, Ukraine (AP) — Russian forces unleashed a nighttime barrage of more than 50 cruise missiles and explosive drones at Ukraine’s power grid Wednesday, targeting a wide area in what President Volodymyr Zelenskyy called a “massive” attack.

The bombardment blasted targets in seven Ukrainian regions, including the Kyiv area and parts of the south and west, damaging homes and the country’s rail network, authorities said. Three people, including an 8-year-old girl, were injured, according to officials.

Russia has repeatedly pounded Ukraine’s energy infrastructure during the war that is stretching into its third year and has claimed thousands of lives. By taking out the power, the Kremlin’s forces aim to rob Ukrainian manufacturing of its energy supply, especially military plants, and crush public morale.

The mass barrages also drain Ukrainian air defenses of ammunition as Kyiv’s depleted forces await delivery of the latest batch of promised Western military support. Ukrainian officials have been pleading for more NATO-standard air defense systems, such as Patriots.
