An RAF helicopter has crashed into a field near Abingdon in Oxfordshire.
It is thought four people were on board the aircraft when it crashed.
A Ministry of Defence spokesman said no one had been injured and the occupants of the helicopter had been taken back to RAF Benson.
Police have cordoned off the crash scene and an investigation into the cause of the accident is now underway.

The aircraft, which is based at RAF Benson, near Wallingford, south of Oxford, came down off the Drayton Road, in Abingdon.
An Ambulance Service spokesman said: "We had a call at about 1409 GMT to attend the aircraft, an RAF Puma, which had crashed into a field off the Drayton Road, in Abingdon.
"We attended with two paramedic ambulances and two officers.
"We have now stood them down - there are no casualties that we are aware of at this time."
