Egypt has unearthed an ancient burial site replete with at least 17 mostly intact mummies. It is the latest in a string of discoveries that the country's antiquities minister described as a helping hand for its struggling tourism sector. <br/><br/>The necropolis, uncovered eight metres below ground in Minya, a province about 250km south of Cairo, contained limestone and clay sarcophagi, animal coffins and papyrus inscribed with Demotic script. <br/><br/>The burial chamber was first detected last year by a team of Cairo University students using radar technology.
