From the Daily Mail:
A knifeman has killed at least 19 people and injured 45 in Japan, according to reports.
It is believed the attacker went into a centre for disabled people in the city of Sagamihara, west of Tokyo, brandishing a knife.
Police were called to the scene at around 2.30am local time after residents saw a man armed with a knife in the grounds of the Tsukui Yamayuri Garden.
Four of the injured are said to be in a serious condition. Local media have reported that 19 people have died and 45 were injured.
Armed police encircled the centre and arrested a man in his 20s on suspicion of murder.
Officers said he was a former member of staff who turned himself in after initially escaping.
The city is known for its US Army base.GO READ THE WHOLE THING.
