Hundreds of South Koreans have marched in one of Seoul's busiest leisure districts to protest the stabbing death of a 23-year-old woman that struck a nerve in a country where many women live in fear of being attacked.

The protesters, many wearing white masks and vinyl coats, began their march Saturday at a gate of southern Seoul's Gangnam subway station, near where the victim was attacked by a male stranger early Tuesday in a building's bathroom.

It was the fourth straight day of memorial events and other gatherings.

The gate has been covered by seemingly thousands of post-it messages, the majority of them apparently from women who expressed grief and fears about potentially becoming random targets of violence. Statistics show violent crimes against women are rising in South Korea.
