Nine people with life-threatening injuries after mass stabbing on train in Cambridgeshire

Ten people are in hospital, with nine believed to have life-threatening injuries, after a stabbing attack on a train travelling in Cambridgeshire.

Two people have been arrested, Cambridgeshire Police say - pictures show officers responding to the scene at Huntingdon station, reports BBC.

Police declare a "major incident" and confirm that counter-terrorism officers will support the investigation.

Passengers were travelling on the 18:25 service from Doncaster to London King's Cross when the attack happened.

An eyewitness tells the BBC they saw a man bolting down the carriage with a bloody arm, saying "they've got a knife, run", and a man collapsed on the floor.

Prime Minister Keir Starmer says the "appalling incident" in Cambridgeshire is "deeply concerning" and urges people to follow the advice of local authorities.
