Archeologists clashed at a conference in Egypt on Sunday over a theory that secret burial chambers could be hidden behind the walls of King Tutankhamun's tomb.

Scans of King Tut's burial chamber have revealed two hidden rooms, Egypt's antiquities minister said Thursday - a discovery that could intensify speculation that the chambers contain the remains of the famed Queen Nefertiti.

Egypt's antiquities ministry says exploration has begun inside King Tutankhamun's 3,300 year-old tomb in the search for hidden chambers that an Egyptologist believes could include Queen Nefertiti.
