Seven children, teacher killed in attack at Chinese school

BEIJING — An attacker hacked seven children and one teacher to death Wednesday and wounded 20 other people in a rampage at a kindergarten in northwest China, the latest in a string of savage assaults at the country's schools.
The slayings occurred despite a countrywide boost in security at schools, with gates and security cameras installed and additional police and guards posted at entrances.
The attack is the fifth major incident at schools and kindergartens in China since late March, sparking security fears among parents, officials and educators.
