Four American military personnel have died after their helicopter crashed in the UK, during a training mission.
The Pave Hawk was taking part in a low-flying exercise when it came down in Norfolk at around 7pm yesterday.
The aircraft was carrying ammunition at the time of the crash, and police are investigating if it poses any risk to the public.
A 400-metre cordon has been set up around the site, at a nature reserve, though residents were allowed to stay in their homes.
The helicopter was based at an RAF base in Suffolk.
The 48th Air Wing of the US Air Force based at RAF Lakenheath said on Twitter: "We can confirm that one of our HH-60G Pave Hawk helicopters was involved in an incident during a training mission outside Cley-Next-The-Sea."
Around a dozen emergency vehicles from the fire brigade, coastguard and police are at the scene.
Superintendent Roger Wiltshire has this update:
A derivative of the more famous Black Hawk helicopter, the Pave Hawk gets its name from the PAVE acronym standing for Precision Avionics Vectoring Equipment.
They are used for combat search and rescue, mainly to recover downed aircrew or other isolated personnel.
They have a four-man crew and can carry up to 12 troops.
