Egyptian protesters tear down a cement wall built to prevent them from reaching parliament and the Cabinet building near Tahrir Square, in Cairo, Egypt, Thursday, Jan. 24, 2013. Egypt's black-clad riot police fired tear gas in fierce dawn clashes with dozens of protesters. The violence which was soothed hours later in central Cairo comes on eve of the second anniversary of Egypt's Jan. 25 uprising, which toppled longtime authoritarian president Hosni Mubarak in 2011.
