President Volodymyr Zelensky of Ukraine said air defenses had shot down at least 30 missiles from a “massive” barrage that had targeted gas and energy facilities.

Moscow launched more than 40 missiles, and at least 30 were shot down, said Ukraine’s President Volodymyr Zelenskyy, adding about 70 strike drones were involved in the attack. It remains unclear how many were intercepted.

The Russian missiles sought out targets from the Lviv region in western Ukraine near Poland to Kharkiv in northeast Ukraine bordering Russia. The state energy company Ukrenergo reported emergency power outages in six regions. It often shuts down production during attacks as a precaution.
