The History Blog has another update on the Egyptian Museum in Cairo.
The two mummies destroyed are only described as Pharaonic which hopefully refers the pre-Greco-Roman time period. It's tragic that any mummies have been destroyed, but I sincerely hope the vandalism didn't involve Pharaohs from the mummy room- that would put Hatshepsut, her father, brother, Seti I, Ramesses II, and many more Egyptian big-names on the list of possible victims.
I'm horrified that there's been some destruction at the hands of looters, but thankful it appears to be contained, at least for now. I'm also relieved to hear of the tanks protecting the Luxor Museum and hope the army grants Zahi Hawass' request to protect the other vulnerable museums and sites around Egypt.
