Zahi Hawass corrects BBC report on new pyramids

ZAHI HAWASS corrects that earlier BBC story about the discovery of seventeen new pyramids etc. via satellite imagery:

Although satellite imaging is useful for discovering new sites and monuments, interpretation of the images is not straightforward. No one can say with certainty that the features displayed under the sand are actually pyramids. Such anomalies could be houses, tombs, temples, pyramids, buried cities or even geological features. The only way we can definitely identify what is there is by excavating it - by investigating it physically. This was not made clear in the article.
