A teenager has been ordered to stand trial in March over the Parsons Green terror attack in which 30 Tube travellers were injured.
Ahmed Hassan Mohammed Ali, 18, is charged with attempted murder and using the chemical compound TATP to cause an explosion that was likely to endanger life.
The Iraqi national, of Cavendish Road, Sunbury, Surrey, made his first appearance at the Old Bailey before Mr Justice Haddon-Cave via video-link from Belmarsh high-security prison.
He wore a grey tracksuit with his shoulder-length dark hair tied back from his face.
Outlining a summary of the charges, prosecutor Lee Ingham said: "The allegation is the defendant built and placed an improvised explosive device on a train and, at or around Parsons Green train station, it partially exploded and the intent was there should be a larger explosion with intent to kill and cause serious injury to people and property."
The prosecutor said the case was regarded as being "motivated by politics" and falls under the Terrorism Act definition.
The defendant spoke only to confirm his name before Mr Justice Haddon-Cave set a timetable for the case.
The senior judge said he intended to preside over the trial at the Old Bailey.
A two-week trial was set to take place on March 5, with a plea and case management hearing on January 19.
The defendant was remanded in custody.
