CAIRO – 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 attack follows smaller scale assaults on women this week in Tahrir, the epicenter of the uprising that forced Hosni Mubarak to step down last year. Thousands have been gathering in the square this week in protests over a variety of issues — mainly worries that presidential elections this month will secure the continued rule by elements of Mubarak’s regime backed by the ruling military.

Earlier in the week, an Associated Press reporter witnessed around 200 men assault a woman who eventually fainted before men trying to help could reach her.

Friday’s march was called to demand an end to sexual assaults.

Around 50 women participated, surrounded by a larger group of male supporters who joined to hands to form a protective ring around them.
