It\'s high time for adults to improve moral education and life skills training to help students deal with conflicts sensibly, said Le Nguyen Quynh Thi from the Ho Chi Minh City Bar Association.

The lawyer made the comment after three students died and three were injured nationwide due to fighting at school.

Pham Van Hoang, a 16-year-old student at Dong Hoi High School in Quang Binh Province, stabbed Vo Nhat Hoan, 16, and Cao Duc Son Ngoc, 18, yesterday. Hoan died at the hospital later in the day.

Ha Minh Cuong, a 15-year-old student at Nguyen Trung Truc Secondary School in HCM City, was killed while fighting with a group of students from Go Vap District\'s Lifelong Education Centre on Monday. One student was seriously injured and hospitalised for treatment.

Last Saturday, Huynh Ngoc Thach, a 18-year-old student at Dak Song High School in Dak Nong Province, killed Nguyen Van Hai after repeatedly stabbing him with a knife. Two other students were seriously injured.

A video clip showing a group of students violently attacking a fellow pupil at Ha Huy Tap High School in Vinh City, Nghe An Province was posted on the internet yesterday. The victim, Nguyen Thi Ha Nhu, was brutally beaten until her mother interfered.

Experts claim that recent school violence has little to do with individual aggression and more to do with rivalries between gangs and groups.
