With scorching temperatures peaking at 97 degrees, a sea of red descended on Gwanghwamun Square in Seoul Saturday.

Thousands of women wearing red shirts endured the suffocating heat for the same purpose — to protest against the illegal filming of women and investigations of sex crimes they say favor men.

Columns of protestors at the square waited to participate well after the afternoon start time. Beginning as far back as the metro station, the crowd of protesters — which organizers placed at approximately 70,000 — sitting facing the Gyeongbok palace as well as those waiting to get in created an endless line.
