Egypt has announced the discovery of a private tomb belonging to a senior official from the 5th dynasty of the pharaohs, which ruled roughly 4400 years ago.

The tomb was found in a buried ridge at the ancient necropolis of Saqqara. It was untouched and unlooted, Mostafa Waziri, secretary-general of the Supreme Council of Antiquities, told reporters at the site. He described the find as "one of a kind in the last decades".

The tomb dates from the rule of Neferirkare Kakai, the third king of the Fifth Dynasty of the Old Kingdom.

Archaeologists removed a last layer of debris from the tomb on Thursday and found five shafts inside, Waziri said. One of the shafts was unsealed with nothing inside, but the other four were sealed. They are expecting to make discoveries when they excavate those shafts starting on Sunday, he said. He was hopeful about one shaft in particular.
