ZAHI HAWASS has another update on Egyptian antiquities: The Sphinx is Sad. He says that the two mummies reportedly damaged in the Egyptian Museum were actually unidentified skulls that were stolen and then recovered without further damage. He also reports that the antiquities at Memphis and Saqqara, as well as various other sites are unharmed. His report on Saqqara is confirmed by a National Geographic article here, mostly based on the reporter's eyewitness testimony.
(HT Dorothy Lobel King on Facebook.)
UPDATE: Lee Rosenbaum has an anonymous report from a French Egyptologist which claims that Saqqara did suffer damage. (Via the Egyptology Blog, entry from 17:36 on Saturday.)
