TAIXING, China - A knife-wielding man attacked a kindergarten class of 4-year-olds in eastern China on Thursday, slashing 28 children in what an expert said was a copycat rampage of two other episodes at Chinese schools in the past month.
A 47-year-old jobless man, Xu Yuyuan, burst into a classroom at the Zhongxin Kindergarten early Thursday, waving an eight-inch (20-centimeter) knife and stabbing a security guard who tried to stop him, the official Xinhua News Agency reported.
Five students were in critical condition following the attack in Jiangsu province's Taixing city and two teachers and the security guard were injured, said Zhu Guiming, an official with the Taixing propaganda department.
A series of school attacks in China in recent years have mostly been blamed on people with personal grudges or suffering from mental illness, leading to calls for improved security.
China's inadequate mental health network has left millions of unstable people without the help they need. Many otherwise healthy Chinese also feel frustrated and powerless because they aren't able to adapt to the constant social upheaval and because they believe the changes favor the corrupt. That kind of anger has occasionally erupted in mass violence and in isolated attacks.
It is not known why schools are targeted.
