Egypt unveils hidden corridor in Giza pyramid
Scientists have discovered a hidden passage inside Egypt's Great Pyramid, the authorities announced on Thursday, part of a seven-year international research project.
The passage is nine metres (30 feet) in length and more than two metres in width, the antiquities ministry said in a statement.
Egypt's Tourism and Antiquities Minister Ahmed Issa told reporters at the ancient site in Giza also known as the Khufu, or Cheops, pyramid, that the "gabled corridor" with a triangular ceiling "was found on the northern face of the Great Pyramid of King Khufu".
