Beijing (AsiaNews / Agencies) - Five children were injured in a kindergarten in Jinan (Shandong) after the assault by a man who then killed himself. The authorities plan to station police officers before kindergartens and schools after a series of attacks and killings against children by frustrated or unbalanced people.

In Jinan, an unidentified man attacked children seriously wounding them but not fatally. Soon after he poured gasoline on himself and set himself on fire, taking two children in his arms, who were rescued by teachers.

Today’s is only the latest in a long series of violence against children. Yesterday, an unemployed man, armed with a knife attacked and wounded 29 children and three adults at a nursery in Taixing (Jiangsu). The police revealed that the man carried out the angry gesture, after "a series of personal and work humiliations."

A day earlier, on April 28, a teacher of 33 years wounded a colleague and 15 pupils in a primary school in Guangdong. The man seems to have mental problems. Hours before the attack, in Fujian, a doctor who was stabbed to death eight children and injured five others last March 23 was sentenced to death. The reason seems to be a fit of rage after being separated from his boyfriend.

The authorities have ordered an operation to prevent attacks by requiring that schools should adopt a full-time security staff that do not permit the entry of unauthorized persons. Each school must provide camera to monitor the interior and exterior of school complexes, as well as students on college campuses.

In Henan, police ordered an increase in patrols that make the rounds in front of schools and check in places frequented by children and young people: internet cafes, video games rooms etc. .. to stop any attacker. In Chongqing, the authorities want to control people with mental disorders who live near schools.

But the implementation of this new security systems is very expensive and the schools and families already have trouble balancing their budgets.
