In pictures: A look back at Hurricane Katrina

Ten years ago, Hurricane Katrina swept buildings off their foundations and deluged nearly all of New Orleans with floodwaters which rose so fast some people drowned in their homes. Those who made it to their rooftops or the relative safety of dry land waited days to be rescued as the Big Easy descended into chaos. Today, colourful homes on stilts have replaced many of the rotting hulks left behind after the low-lying coastal city in the southern United States was finally drained.
