Ukraine has used British-supplied Storm Shadow missiles in Russia for the first time.

The Telegraph understands that residents in the village of Marino, Kursk, found fragments from a Storm Shadow missile on Wednesday.

The use of Storm Shadow missiles comes after Russia launched a counteroffensive in Kursk, which was invaded by Ukrainian troops in August.

It also follows Joe Biden’s decision to give Ukraine the green light to use US-made long-range missiles inside Russia earlier this week.

Kyiv first used Atacms to strike a military facility in Bryansk early on Tuesday.

Vladimir Putin responded by lowering the threshold for firing nuclear weapons at Ukraine and its allies.
