Russia now poses a more dangerous and complex threat to the United Kingdom and NATO than at any point in recent decades, requiring a “whole of society” response that goes far beyond the armed forces alone, Britain’s top military officer said during a major security speech in London.

A Ukrainian underwater drone struck and critically disabled a Russian Project 636.3 Kilo-class submarine inside the Novorossiysk naval base. Ukrainian analysts say the strike effectively removes the submarine from service due to Russia’s inability to repair submarines in the Black Sea, while blast fragments from the explosion may have also damaged a second submarine moored nearby.
