Chinese state media say a man stabbed 22 children and an adult at an elementary school in central Communist China on Friday.
The official Xinhua news agency says the knife-wielding man attacked the children outside a school in Chenpeng village in Henan province. It said the children, whose ages are not known, suffered non-life-threatening injuries.
Police say the attacker was later detained, but gave no motive for the stabbings.
Schools in China have increased security following a series of deadly attacks on students in recent years.
The most recent was in August, when a man broke into a middle school in the southern city of Nanchang and stabbed two students.
In March 2010, a man described as an unemployed middle-aged doctor killed eight children with a knife at a school in the southern city of Nanping.
Some observers say the attacks have highlighted a weakness in the Chinese medical system's ability to diagnose and treat psychiatric illnesses, which have been on the rise. VoA.
