Islamist protesters spray the name of former Egyptian military chief Field Marshal Mohamed Hussein Tantawi on a signboard, to rename the square the signboard refers to, near the main entrance of the state security headquarters in Cairo May 2, 2013. Egyptian security forces fired tear gas to disperse a small group of hardline Islamist protesters who were attempting to scale the walls of the state security headquarters in a Cairo suburb late Thursday night.
