Scans in King Tutankhamun's tomb in Egypt's Valley of the Kings point to a hidden chamber, the country's antiquities minister said Saturday, possibly heralding the discovery of Queen Nefertiti's resting place.

"We can now say that we have to find behind the burial chamber of King Tutankhamun another chamber, another tomb," Mamduh al-Damati said at a press conference, speaking in English.

He said experts were "approximately 90 percent" sure. The tests were spurred by a study by renowned British archaeologist Nicholas Reeves that said Nefertiti's lost tomb may be hidden in an adjoining chamber.
