The attack occurred about 8 a.m. at a kindergarten in Nanzheng County, in Shaanxi Province, Xinhua said.
There were few details immediately available about the incident, the latest in a perplexing and horrifying string of attacks on young Chinese schoolchildren in recent months.
On March 23, Zheng Minsheng, 42, stabbed eight primary school students to death in Fujian Province, on China’s eastern coast. Mr. Zheng reportedly had mental problems, although most state media said no such evidence existed.
After a speedy trial, Mr. Zheng was executed on April 28, the same day that 16 children and their teacher were attacked at a primary school in the southern province of Guangdong.
Update: Reuters has more details about Wednesday’s attack:
A 48-year-old man, Wu Huanming, used a kitchen cleaver to kill five boys and two girls as well as the mother-son team who owned and ran the private kindergarten, Xinhua said.
Wu then returned home and committed suicide, Xinhua said, citing a statement from the province emergency office. “His motive for the attack was not immediately known,” it said.
One local man, Zheng Xiulan, said the attacker had rented out the rooms for the privately run kindergarten, located in a row of low houses with concrete yards.
“Only about two of the children in the kindergarten were not injured, but I don’t know how many died in the end. There was blood everywhere,” Zheng told Reuters by telephone.
“I don’t know why he did it … I hadn’t heard that he was mentally ill. He wasn’t poor either.”
