Tensions between Russia and the United Kingdom have escalated sharply after London accused a Russian vessel, Yantar, of directing lasers at British military pilots while sailing near British waters. The incident, confirmed by Defence Secretary John Healey, has raised new concerns about Russian surveillance of critical undersea cables and infrastructure.
