[00:00.00]Now to Egypt.
[00:01.95]Among the demonstrators who jam Tahrir Square every day are hundreds of women. 
[00:05.91]They face a very disturbing threat from gangs of men who sexually assault female protesters.
[00:11.53]Lindsey Hilsum of Independent Television News reports from Cairo.
[00:14.72]And a warning: You may find some of the details and the images in her story distressing.
[00:22.22]Such sweet boys full of energy and fun. 
[00:25.26]They have just been chasing a young woman up the street. The interviewer asks them why.
[00:33.22]"If a lady is respectable, no one will harass her," says a kid in red. 
[00:38.07]The others pile in. "Why do they wear short skirts or tight trousers?"
[00:42.42]"Some young women, when we flirt with them, they smile."
[00:45.88]That's how it starts. This is how it ends. 
[00:51.95]A mob attacks a young woman on the corner of Tahrir Square. We have disguised her identity.
[00:57.97]This is one of more than a hundred assaults in Tahrir Square during last week's demonstrations. 
[01:04.35]This is the very place. Women still come to the square, but it's dangerous.
[01:10.17]This corner of Tahrir Square has become notorious for attacks on women. 
[01:14.57]I can only come here tonight because it's almost empty because of Ramadan and people are praying. 
[01:20.19]And I have got a whistle to protect me and an alarm and a whole crew of people around me. 
[01:25.56]That's not the case for many women who come here.
[01:28.65]And the most horrific thing I have heard is that these attacks are planned, and, 
[01:32.90]sometimes, women think that the men coming for them are trying to save them from being assaulted, 
[01:38.78]but in fact they take them away and attack them again.
[01:42.41]A long darning needle. 
[01:44.30]Janet Abdel Aleem and her group of activists distribute the needles to women for self-defense. 
[01:50.17]She and her colleague Nada were assaulted in Tahrir Square last November.
[01:58.18]They were putting their hands into my pants and into Nada's pants and inside my blouse, touching me everywhere. 
[02:05.26]There were about 15 to 20 people who said they were trying to protect and save us, but they suddenly started to attack us.
[02:13.41]Today, the Muslim Brotherhood are on the streets. 
[02:16.60]The women tell me it's the secularists in Tahrir Square, not religious men, who do it.
[02:21.96]No, that's in Tahrir Square, not here; 170 women get raped in Tahrir Square, 
[02:28.29]because I don't know which kind of people is going to Tahrir Square. 
[02:31.97]Maybe it's the people, they freed them when they open prisons.
[02:35.36]But both political factions have tried to intimidate women off the streets at different times.
[02:41.79]And the Muslim Brotherhood blocked a law on violence against women.
[02:45.99]Law and order collapsed under their rule, so voluntary groups had to step in.
[02:50.96]We're doing the job of the police.
[02:53.40]We're doing the job of people who are in power who should be responsible for this.
[02:59.61]Zeinab is planning to join her male colleagues intervening to save women being attacked in Tahrir Square, 
[03:07.05]because the victims now fear that rescuers may in fact turn out to be rapists.
[03:12.26]I reached the point where I don't get scared anymore. 
[03:18.06]Now when someone touches me when I'm trying to, not intervene, but patrolling at least, or anything like that, 
[03:24.71]it's never fine. But kind -- I know it's part of the job, like, it's something that you cannot prevent for now.
[03:31.35]But when it comes to intervening, I saw cases. I saw victims and I -- 
[03:36.76]it's traumatizing, and I see them. And I feel that it's not -- you cannot trust a man anymore.
[03:42.72]Poverty, unemployment, segregation of the sexes, many factors contribute to endemic sexual harassment in Egypt. 
[03:50.67]But deprivation in social attitudes are not the only causes.
[03:56.89]The problem is, there's no law against this. 
[03:59.27]People know if they go into the square and touch women, they will not be punished. 
[04:03.71]Also, us women are blamed for being harassed. We shouldn't blame women for this.
[04:14.11]In Tahrir Square, they're holding Ramadan prayers just next to the place where women are frequently raped. 
[04:21.09]Mob assaults and escalation of sexual harassment are the unintended consequence of a revolution that was meant to liberate Egyptians, men and women alike.
[04:33.24]The Muslim Brotherhood and other groups are calling for a million man demonstration tomorrow in Cairo. 
[04:38.67]Its aim is to protest President Morsi's ouster and clashes with Egypt's military that left more than 50 people dead.
