Two firefighters and a member of the public have died following a large fire at a former RAF base. Oxfordshire County Council said the two firefighters died while tackling the blaze at Bicester Motion on Thursday.
Two further firefighters suffered serious injuries and are currently in hospital, the council added.
Ten fire and rescue crews were called to tackle the fire, which prompted a major response and warnings for local residents to stay indoors.
The council said four crews remain at the scene as the blaze is now under control.
Chief fire officer Rob MacDougall said: “It is with a very heavy heart that we today report the loss of two of our firefighters.
“Families have been informed and are being supported.”
