Public bathrooms in all transportation hubs in South Korea, including airports, bus terminals, metro and train stations, will be regularly monitored as a measure to better deal with secret cameras installed in public toilets, as well as spy cam pornography that has been prevalent in the cyberspace in the country, its government announced Sunday.

Tens of thousands of South Korean women staged a mass rally in Seoul Saturday to protest against spycam porn, urging tougher punishments for peeping Toms as anger over the growing scourge boils over.
