Egypt's antiquities ministry says new radar scans have provided conclusive evidence that there are no hidden rooms inside King Tutankhamun's burial chamber.

The Sunday statement by Mostafa Waziri, Secretary General of the Supreme Council of Antiquities, says an Italian team conducted extensive studies with ground-penetrating radar that showed the tomb did not contain any hidden, man-made blocking walls as was earlier suspected. Francesco Porcelli of the Polytechnic University of Turin will present the findings later on Sunday.

In 2015, British Egyptologist Nicholas Reeves proposed, after analysis of high-definition laser scans, that queen Nefertiti's tomb could be concealed behind wall paintings in the famed boy king's burial chamber.

The ministry says previous scans by Japanese and American scientists had proved inconclusive.
