An explosion on board a Tube train at Parsons Green station is being treated as terrorism, Scotland Yard has said.
As many as 18 passengers were injured after a bucket exploded and caused what witnesses described as a “fireball” at 08:20 at the District Line station in south-west London.
The blast does not appear to have caused major damage to the Tube carriage, but it did cause panic and confusion amongst commuters who rushed out of the station, resulting in a number of injuries from the stampede.
One commuter managed to video the smouldering bucket, described by police as an “improvised explosive device” or IED, after the incident.

The London Ambulance Service sent a number of ambulance crews and a “Hazardous Areas Response Team” to the scene, but said that none of those injured are thought to be in a serious or life-threatening condition.
The Metropolitan Police have cordoned off the station and advised people to avoid the area as the carry out an investigation into the cause of the explosion.
The government’s emergency committee, Cobra, is meeting at 13:00 BST.
In statement, London Mayor Sadiq Khan appealed for calm and said:
“Our city utterly condemns the hideous individuals who attempt to use terror to harm us and destroy our way of life.
“As London has proven again and again, we will never be intimidated or defeated by terrorism.”
Prime Minister Theresa May tweeted:
“My thoughts are with those injured at Parsons Green and emergency services who are responding bravely to this terrorist incident.”
