An elementary school guard in China injured 39 people in a knife attack yesterday with many children among the victims, a state office and media reported. Two of the injured were severely hurt in the attack in the southwestern region of Guangxi, the county-level propaganda office said on its social media account. Others sustained light injuries and no one was critically hurt, it said. The suspect, a 50-year-old man surnamed Li who worked as a guard at the school in the town of Wangfu, attacked at around 8:30 am, according to the Paper, a Shanghai-government backed newspaper. Li has been arrested. Many of the injured children were about six years old. China has seen several attacks on schoolchildren in recent years, with eight children killed in a similar attack in Hubei province last year.
