Origins: We do not yet know the specific origins of these pictures, but the contextual information accompanying them does correspond to a real event, and they match other photos of the same phenomenon: a dust storm which struck Al Asad in the western desert of Iraq on 26 April 2005.
According to a Marine Corps News article:
As the storm moved closer the sky changed to a shade of orange until total darkness blanketed the ground. The storm passed over in about 45 minutes, leaving a heavy sheet of dust in its wake. Forecaster say the wall of dust may have reached 4,000 to 5,000 feet.
This dust storm was a spectacular sight and may look worse than it actually was. No one was injured and no equipment was damaged here.
