WATCH: Wall of dust sweeps across Arizona

A 50-mile-wide wall of dust has swept across parts of Arizona in the US, with local news outlets reporting that some 7,000 properties had been left without power.

The dust wall, also known by its Arabic name of haboob, was up to 6,000ft (1,828m) at its tallest point and reached speeds of up to 65mph (104.6km/h).
