Egypt's tourism and antiquities minster said on Saturday archaeologists have unearthed dozens of ancient coffins in a vast necropolis south of Cairo.
Khalid el-Anany said at least 59 sealed sarcophagi, with mummies inside most of them, were found that had been buried in three wells more than 2,600 years ago.
"I consider this is the beginning of a big discovery," el-Anany said, adding that there is an unknown number of coffins that have yet to be unearthed in the same area.
He spoke at a news conference at the famed Step Pyramid of Djoser in Saqqara where the coffins were found. The sarcophagi have been displayed and one of them was opened before reporters to show the mummy inside. Several foreign diplomats attended the announcement ceremony.
