A huge Ukrainian installation at the Burning Man festival in Nevada called the Black Cloud - a visual metaphor for the looming threat of war - was destroyed by a powerful storm which hit the site at the weekend. High winds created a "wall of blowing dust" which reduced visibility to near zero. People trying to get into the festival faced traffic jams of up to eight hours. #Ukraine #BurningMan #Ukrainewar #Channel4News #C4News | Channel 4 News
