Last weekend heavy storms crashed through Yemen, one of the poorest countries in the world. The wind, rain and lightning killed a number people initiallly, but the subsequent flooding took a much larger toll, in both lives and property. The hard-hit Hadramaut region is home to the ancient walled city of Shibam, a UNESCO World Heritage Site, nicknamed the "Manhattan of the desert". The structures in Shibam and neighboring villages are mud-brick construction, and were damaged badly by the rain and flooding, many collapsing when their foundations were undercut. The World Health Organization has estimated that 180 people have died, mostly in building collapses, though that number is likely to change as debris is cleared away. ( 22 photos total
