This sounds so awful - an eagerly awaited festival descending into chaos because of flooding and rain in the desert closing all roads in and out. I hope no families with children are trapped
Those poor people - toilets and running water no longer working, no estimate of end date. Warned to remain warm and under shelter if possible, and ration their personal food and water.
I am assuming it is possible for supplies to be flown in by helicopter if necessary, even if it can't land.
If anyone on Mumsnet is there, sending you lots of love and best wishes
