Beijing (CNN) – A man in southern China stabbed 10 schoolchildren before killing himself Monday morning, state-run media reported.
All of the children survived and were hospitalized, the state-run Xinhua news agency reported.
The incident took place in Haikou, the capital city of the southern island province of Hainan.
The motive for the attack remains unclear.
China has seen a spate of stabbing attacks at schools in recent years.
In 2014, a man fatally stabbed three children at a primary school in central China and then committed suicide by jumping off a building, Xinhua reported at the time.
An initial investigation suggested that attacker was upset that his daughter was not allowed to attend the school after failing to complete a summer homework assignment, Xinhua said.
In 2012, a man raced toward a school gate in Henan province, flailing a knife as terrified youngsters tried to flee. He chased the students and wounded 23 of them.
Police said that attacker was driven to commit the attack by “doomsday” rumors, Xinhua said at the time. Authorities also said Min testified he was inspired by TV reports about a kindergarten killing in 2010.
