Ministry says Briton, who has not publicly been named, was injured while observing a test, away from the frontline

A member of the UK armed forces was killed in an accident in Ukraine on Tuesday morning, believed to be the first time a serving member of the British military has been killed in the country since the full-scale Russian invasion.

The victim was not immediately named, though the Ministry of Defence said their family had been notified, after an incident that appears to have taken place during a weapons test at a site away from the frontlines.
