Overview
- The Ministry of Defence confirmed the Yantar is on the edge of UK waters north of Scotland after entering the UK's wider waters in recent weeks.
- A Royal Navy frigate and Royal Air Force aircraft have been deployed to monitor and track the vessel continuously.
- British officials say the ship directed lasers at RAF pilots during surveillance flights, which the defence secretary called extremely dangerous.
- Royal Navy rules of engagement have been adjusted to enable closer tracking, and ministers say military options are ready if the ship turns south.
- UK officials describe Yantar as designed for intelligence gathering and undersea‑cable mapping, and Russia has previously dismissed such accusations as unfounded.
