A supporter of Egypt's ousted President Mohammed Morsi wears buttons showing Morsi and an open palm with four raised fingers, which has become a symbol of the Rabaah al-Adawiya mosque, where Morsi supporters had held a sit-in for weeks that was violently dispersed in August, during a protest in Cairo, Egypt, Friday, Oct. 11, 2013. Thousands of Morsi supporters took to the streets Friday in several cities, commemorating 100 days since Egypt's first democratically elected president was ousted by the military following mass protests calling for his resignation. The Arabic on the button reads,"Rabaah, up, Morsi my president." (AP Photo/Hassan Ammar) ( Mideast Egypt )
