Jordan: Petra's tourism authority cracks down on Bedouin cave dwellers One of the Seven Wonders of the World, the ancient city of Petra in Jordan welcomes several hundred thousand tourists each year. It dates back to 300 BC and has been a UNESCO World Heritage Site since 1985. For centuries, Bedouins have inhabited its caves, but many have recently been forced to leave and relocate to government housing. Some families have chosen to remain, although they could be expelled at any moment. It's becoming increasingly difficult for them to make a living through tourism, their main source of income. Our Jordan correspondent went to meet them.
