CAIRO, EGYPT—Egypt’s Antiquities Minister Mamdouh Eldamaty announced at a press conference that the recent ground-penetrating radar survey of Tutankhamun’s tomb, conducted by Hirokatsu Watanabe, suggests that there could be two chambers behind the north and west walls of the tomb’s burial chamber. The study also suggests that there are doorways and metal and organic materials within the spaces. Additional radar scans will be conducted in collaboration with scientists from Cairo University at the end of the month. “It is a very important step in an attempt to explore these two walls and find the correct and safe methods to uncover what lies behind them,” Eldamaty told Ahram Online. He thinks the chambers could hold the remains of Tutankhamun’s sister, Merit aatun, his mother Kia, or his grandmother Tiye. To read more about Tutankhamun, go to "Warrior Tut."
