British police say there is nothing to suggest a mass stabbing incident on a train on Saturday was a terrorist incident. Doctors continue to treat seven passengers, two of whom have life-threatening injuries. Armed police arrested two suspects at Huntingdon station in Cambridgeshire, where the train made an emergency stop after terrified passengers alerted the crew.
