Russia’s military on Tuesday said it would retaliate against Ukraine after Kyiv attacked Russian regions by firing six US-made ATACMS ballistic missiles, six UK-made Storm Shadow cruise missiles and launching one of the biggest drone attacks to date.

Russia launched scores of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in a new barrage against the struggling power system in the depths of winter.

Ukrainian officials say Russia has launched a major ballistic and cruise missile attack on regions across Ukraine

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.
