Another woman, aged in her 20s, was taken to hospital where she is being treated for smoke inhalation and remains under observation. Essex Police officers are now working with firefighters who are investigating the cause of the blaze, which remains unknown at this stage. A spokeswoman for the force said: Our thoughts are with those who have been impacted by today’s tragic events. One elderly couple, whose lodge was just metres from the fire, said: “We were watching Jeremy Vine on the television when we started to smell smoke. “There were people shouting and then all we could see were flames that were 15ft high - they were above all the other vans.
