From afar, Tahrir Square appears almost festive as protesters chant against the Islamist president who was overthrown by the Egyptian military last week. But inside the crushing crowds, the scene can be a lot more sinister.
In a video posted by the Muslim Brotherhood, an unidentified woman cries out as men attack her. The group, from which former President Mohammed Morsi hails, claims the attack occurred in Tahrir Square in late June.
Human Rights Watch reports a sharp rise in sexual assaults here since anti-Morsi protesters took to the streets in record numbers last week. Activists report more than 100 sexual assaults in or near Tahrir Square during the past week alone, many of them gang rapes.
