Luxor and Giza Sites Under Military Guard

The Associated Press reports that Egyptian authorities have set up barriers to protect Karnak Temple--the world's largest ancient religious site--in Luxor. In addition, tanks were stationed outside Luxor's museum. This information was reportedly supplied by American archaeologist Kent Weeks, who is in Luxor and heads the Theban Mapping Project.

Meanwhile, the Giza pyramids have been closed and placed under military guard.
