Hello and welcome to NewsHour.
It's coming to you live from the BBC World Service Studios in central London.
I'm Tim Frakes.
We're going to begin with a remarkable bit of testimony of a young woman who witnessed a moment,
actually several minutes, of horror aboard an English train pretty much this time last night.
It was when the express from Doncaster in the north of England was about halfway through its journey down to London.
Suddenly there was a mass stabbing.
Within a few minutes the train driver was able to divert and come to an unscheduled stop at a station.
Armed police poured forth.
Two British-born men were initially arrested,
although only one is now being held on suspicion of attempted murder.
Eleven people needed treatment in hospital, of whom one remains in a life-threatening condition.
As I mentioned, in a moment we'll hear from a passenger.
But first, with the latest, here's our UK correspondent Daniel Samford.
And Daniel of...
the people still in hospital or the person still in hospital.
What have you said?
Yeah,
I mean this time last night there were nine people with life-threatening injuries in hospital in Cambridge.
