LONDON -- London's Metropolitan Police said a fire on the London subway has been declared a "terrorist incident."
The force said counterterrorism officers are leading the investigation into the incident at Parsons Green station, where "a number" of people have been injured.
Passengers reported an explosion in a carriage of the train shortly after 8 a.m., during the morning rush hour. Several people appeared to have burn injuries.
Police said it's "too early to confirm the cause of the fire, which will be subject to the investigation that is now underway by the Met's Counter Terrorism Command." (AP)
