Japan’s national broadcaster NHK reports that 15 people were killed and 45 injured in a knife attack Tuesday at a facility for the handicapped in Sagamihara, just outside Tokyo.
The report said police have arrested a knife-wielding man after he turned himself in.
NHK said the suspect, 26, is a former employee at the facility, Tsukui Yamayuri-en, on suspicion of attempted murder.
Television footage showed a number of ambulances parked outside the facility, with medics and other rescue workers running in and out.
Kyodo News agency reported that 19 people are dead and 20 injured, including those in a condition of heart and lung failures.
Police say the knife-wielding man entered the facility and began attacking just after 2:30 a.m. Tokyo time.
The attack comes four days after a 17-year-old Afghan refugee slashed five people on a train in Germany before being shot dead by police.
