In the worst mass killing of its kind in generations in Japan, at least 19 people were killed and about 20 wounded in a knife attack at a facility for the disabled in a city just outside Tokyo. Police said they responded to a call at about 2:30am Tuesday from an employee saying something horrible was happening at the facility in the city of Sagamihara, which is 30 miles west of Tokyo, reports the AP. A man turned himself in at a police station about two hours later. He left the knife in his car when he entered the station, police say. Officials in Kanagawa prefecture, which borders Tokyo, identified the suspect as Satoshi Uematsu, and said he had worked at the facility until February. Japanese media reports said he was 26 years old. (More Japan stories.)
