UK Prime Minister Theresa May will chair a meeting of the Government's Cobra emergencies committee this afternoon to discuss the terrorist incident at Parsons Green, the Express.co.uk reports. 

A fireball ripped through a London Underground train at Parsons Green at 8.20am.

Scotland Yard are treating the explosion on the train, which was full of rush hour commuters heading into Central London, as a terrorist incident.

Prime Minister Theresa May is being regularly briefed as armed police surround the scene. She will chair the Government's Cobra emergencies meeting at 1pm.

Mrs May said: "My thoughts are with those injured at Parsons Green and emergency services who are responding bravely to this terrorist incident."

Witnesses described the train involved in the explosion as "absolutely packed".

Commuters fled in terror after a blast sent a "fireball" and a "wall of flame" through a packed London Underground train.

Eyewitnesses reported seeing several people hurt and "covered in blood" after a "flash and a bang" on the District Line Tube in West London.

Police have not given details about the suspected cause of the explosion but the incident comes with Britain on high alert after four terror attacks in 2017.
