INTERNATIONAL NEWS - An explosion on a Tube train in south-west London is being treated as terrorism, Scotland Yard has said.
Passengers were injured following the blast at 08:20 BST (07:20 GMT) at Parsons Green station.
Pictures show a white bucket on fire inside a supermarket bag, but do not appear to show extensive damage to the inside of the carriage.
The Metropolitan Police said "a number of people" had been injured and advised people to avoid the area.
It was too early to confirm the cause of the fire and the station has been cordoned off, the statement said.
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."
The government's emergency committee, COBRA, is meeting at 13:00 BST.
