One person has died at Burning Man in Nevada amid a weekend of rain and mud which has seen festivalgoers forced to shelter in place.

The Pershing County Sheriff's Office in northern Nevada said the death happened 'during this rain event' but gave few other details as to what the cause was, or the person's identity.

'As this death is still under investigation, there is no further information available at this time,' the sheriff's office said in a statement on Saturday night.

Tens of thousands of revelers attending the event in the Nevada desert were told to stay put and conserve food and water on Saturday after a massive rainstorm turned the site into a mud pit.
