They had a sign?
U.S. troops sweeping through Fallujah on Thursday said they believe they have found the main headquarters of the insurgent group headed by Jordanian terrorist Abu Musab al-Zarqawi.

In video shot by an embedded CNN cameraman, soldiers walked through an imposing building with concrete columns and with a large sign in Arabic on the wall reading "Al Qaida Organization" and "There is no God but Allah and Muhammad is his messenger."

Inside the building, U.S. soldiers found documents, old computers, notebooks, photographs and copies of the Quran.
