Egyptian archaeologists have found the remains of a mummy thought to be that of Queen Seshestet, the mother of a pharaoh who ruled Egypt in the 24th century BC, the government said on Thursday.

After five hours spent lifting the lid of a sarcophagus in a pyramid discovered south of Cairo last year, they found a skull, legs, pelvis, other body parts wrapped in linen, and ancient pottery, the government's antiquities department said.
