In Egypt, thousands of men and women have marched against the sexual harrassment of female protestors.

More than 20 women were sexually assaulted last month during the second anniversary of the so-called “Arab Spring” protests that led to the downfall of Hosni Mubarak, former president.

But sexual violence is nothing new in Egypt, one study estimates that more than 80 percent of women have experienced it at least once.
