Archaeologists have discovered eight limestone sarcophagi with mummies inside around 25 miles south of Cairo, Egypt.

The Antiquities Ministry said the mummies date back to the Late Period (664-332 BC) and are covered with a layer of painted material, called cartonnage, in the form of a human.

Only three of the mummies were in a good condition of preservation, Dr Mostafa Waziri, secretary-general of Egypt's Supreme Council of Antiquities, explained.

Dr Waziri said photos of the discovery would be exhibited in museums which are due to open in Hurghada and Sharm el-Sheikh.

The ministry said the mummies were found in an area of King Amenemhat II's pyramid in the Dashur royal necropolis, which was the burial site for courtiers and high-ranking officials.

The area is home to what are believed to be some of the earliest pyramids, including Sneferu's Bent Pyramid and the Red Pyramid.
