The Los Angeles Times reports on a new attack on school children in China:

The brutal killing of at least three children and a teacher at a school in northeastern China had residents confounded and authorities tight-lipped on Wednesday.

A man identified by state media as Fang Jiantang, 26, reportedly attacked kindergarten students and teachers with a knife Tuesday in a suburb of Zibo, killing four and injuring 20 staff and children. The man turned himself in to police, according to Singtao Daily, a Hong Kong newspaper. A 2-foot-long knife believed to be the weapon used in the attack was recovered. No motive has been established.
