According to various sources linked by Vlad Tepes, the man who attacked soldiers at the Carousel du Louvre is an Egyptian who arrived at the Roissy Charles de Gaulle airport on a flight from Dubai. He had no explosives, but had two backpacks in which he carried a cell phone, a machete and paint bombs. He was shot in the "flanks" and the rear end, and was hospitalized.
The thought of the damage paint bombs could do to the contents of an art museum should be truly horrifying. Read the story at Vlad Tepes, and be sure to check out the comments thereto. I would especially recommend a comment posted by someone calling himself Green Infidel, which reproduces a comment left on Jihadwatch by an archaeologist who tried to visit petroglyph sites in Pakistan.
