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.

As snow fell in a wooded area of Ukraine, the long-range attack drones accelerated one by one down an unlit, abandoned road and their whirring engines propelled them into the night sky.

Kyiv says it struck a Russian oil refinery and a microchip factory in attack which Moscow says contained 120 drones
