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.

Air defences were engaged in Ukraine's capital of Kyiv on Thursday to repel a Russian drone attack, officials said, and Reuters witness reported explosions in the city while British Prime Minister Keir Starmer was visiting.
