Attackers sometimes go after schoolchildren in China, just as they do in the USA.
My very unscientific survey, though, has no shootings, but knives, hammers, SUV, axes, bombs, chemicals have been used.
Fifty-one children and three teachers were injured at a kindergarten in southwest China when a man attacked them with a corrosive chemical, state media reported Tuesday.
According to state-run news agency Xinhua, a 23-year-old suspect surnamed Kong climbed into the school in Kaiyuan city, Yunnan province, on Monday afternoon and sprayed caustic soda on a room full of students and teachers.
Two of those hit were seriously hurt, although their injuries are not life-threatening, the report said.
Back in September, 8 children were killed in this attack.
I found this entry on Wikipedia describing attacks from 2010 to 2012.
After that, security guards were deployed to schools. It’s hard to gauge the effectiveness of those guards in deterring attacks or limiting harm.
This writer speculates on the cause, in the New Republic.
