Scientists have discovered a hidden passage inside Egypt's Great Pyramid, part of a seven-year international research project. The passage is nine meters in length and more than two meters 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." The discovery was part of the ScanPyramids project, launched in 2015 as a collaboration between major universities in France, Germany, Canada and Japan and a group of Egyptian experts.
