United News International (UNI)- Thousands of women in South Korea joined together in Seoul July 7 to demand more government involvement in the fight against hidden sex cameras.

This was the largest all-female protest to take place in South Korea.

Demonstrators were encouraged to wear baseball caps, sunglasses and surgical masks to hide themselves.

Women are fighting for protection from people who hide cameras in public places to capture nudity and post the footage on the internet.

Though distributing pornography is illegal in South Korea, the hidden camera footage still circulates widely.

The number of hidden and up-skirt cameras in South Korea rose from 1,100 to more than 6,500 in the past eight years.

South Korea President Moon Jae-in in response to the crisis said, “We must make sure that the offenders suffer greater damage than the damage they inflict.”
