Daejeon Fatal Stabbing

The incident occurred just two months after a teacher fatally stabbed a student at an elementary school in the country.

The incident occurred in the central city of Daejeon.

The female teacher was found with self-inflicted injuries to her neck and hands.

Authorities had said she had mental health issues and had previously taken medical leave since she suffered from depression, media reports said.

The incident had left the country shocked and even raised questions about the security of students in schools.

South Korea is a generally safe country with strict gun control laws. But in recent years, it has grappled with several high-profile crimes, including stabbings, BBC reported in February.
