Witnesses described scenes of terror and panic as the blast sent a "fireball" and a "wall of flame" through a District line service at Parsons Green station in west London.

Police suspect the explosion was sparked when an improvised explosive device was detonated, and have launched a huge counter-terrorism investigation alongside MI5.

The device is being forensically examined while detectives are scouring CCTV and examining witness statements for potential leads.
