Eleven people injured in violence that also left two others dead on Wednesday in suburban Shanghai remained hospitalized on Thursday, as witnesses praised those who subdued the knife-wielding assailant.
Ai Kaixing, president of Fengxian Central Hospital, said that most of the injured - including six children, 8 to 10 years old - were wounded on their heads by the assailant, who slashed the victims with two knives.
The hospital brought in orthopedists and neurosurgeons to treat the victims, Ai said. None of the injuries is considered life-threatening.
The city's education commission demanded that all kindergartens and primary and middle schools improve their campus security.
The commission alerted the institutions to increase security forces to guard the school gates and said the gates must be shut while students are in class.
Police said the investigation is continuing, and a test has yet to be done on the suspect's mental condition.
