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.

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

Russia launched a large-scale missile attack on Wednesday, some slamming into energy facilities that caused power losses in several regions of the country, officials said.
