At least 19 people have been killed and many others injured in a knife attack at a facility for the disabled in Sagami-hara, just outside Tokyo this morning.

Police say they responded to a call about 2:30 am local time from an employee saying something horrible is happening. A man turned himself in at a police station about two hours later.

CCTV correspondent Terry Terashima now joins us from Tokyo with more.
