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.

The barrage appeared to be one of the largest recent assaults in Ukraine’s campaign to damage Russia’s war machine on its home territory.

Ukrainian forces used missiles and drones on Tuesday to target sensitive military and energy sites across Russia.

Ukraine struck Russian regions with a major drone and missile attack overnight, damaging at least two factories and forcing schools to close in a major southern Russian city, according to Russian officials and media.

Ukraine used six British Storm Shadow missiles and US-made Atacms tactical ballistic missiles in what Kyiv described as its “largest attack” on Russian military facilities.

An air-raid warning has been issued across Ukraine on the morning of 15 January due to the threat of missile strikes.
