A mob of hundreds of men assaulted women holding a march demanding an end to sexual harassment Friday, with the attackers overwhelming the male guardians and groping and molesting several of the female marchers in Cairo’s Tahrir Square.

From the ferocity of the assault, some of the victims said it appeared to have been an organized attempt to drive women out of demonstrations and trample on the pro-democracy protest movement…

The marchers tried to flee while the attackers chased them and male supporters tried to protect them. But the attackers persisted, cornering several women against a metal sidewalk railing, including an Associated Press reporter, shoving their hands down their clothes and trying to grab their bags. The male supporters fought back, swinging belts and fists and throwing water.

Eventually, the women were able to reach refuge in a nearby building with the mob still outside until they finally got out to safety.
