A debris flow of ice, water and sand?

A debris flow of ice, water and sand?

Just when you think you have seen it all, this pops up on Youtube:-

This event was apparently associated with the very heavy rainfall across the Middle East at the end of October and first half of December, as described by NASA.  This debris flow appears to have been the result of a very heavy hailstorm, but I know no more.  A still from the video,suggests that there is a large concentration of hailstones in it:

I have never heard of such a debris flow, but am no expert on processes in deserts.  I don’t even know if it is for real, though it does not look fake on first inspection.  Does anyone know more?

Hat tip to Phil Ashworth on Twitter for coming across this one.
