London’s Metropolitan Police say they are investigating a fire and reported explosion on a London Underground train in southwest London on September 15 as a “terrorist incident.”
Police confirmed a fire on a train during the busy morning rush hour at Parsons Green station, an above-ground station on the Wimbledon branch of the London subway system’s District line.
Authorities said it was “too early to confirm” the cause of the fire.
Initial British media reports said a white container "exploded" on the train. But Sky News later quoted a police official as saying that a suspected explosive device did not fully detonate.
One witness told Reuters he was on the train at Parsons Green when he heard a "whoosh" and saw the next car become engulfed in flames.
Police said there were multiple injuries, including cases of people suffering from facial burns. There were no immediate reports of deaths.
Armed police were on the scene, while ambulance crews were treating the injured.
Prime Minister Teresa May said she would chair a meeting of the National Security Council later on September 15.
