Egyptian scholar Samuel Tadros tells me that observers in Cairo are seeing Islamists out in full force among the protesters today for the first time since the demonstrations began. They poured out of the mosques after Friday prayers and are marching and shouting Islamist slogans. Protesters continue to take to the streets one hour into the curfew. Alexandria, where police withdrew hours before the military was deployed, reportedly remains out of government control and in chaos, with looting and fire-setting.
