An Egyptian protester hold up his hand with a slogan reading in Arabic: "Egyptian girls are a red line" during a demonstration in Cairo against sexual harassment on February 12, 2013. Egyptian protesters took to the street again to demand an end to sexual violence, as campaigns against the repeated attacks in central Cairo pick up steam. Sexual harassment has long been a problem in Egypt, but recently the violent nature and frequency of the attacks have raised the alarm.
