A teenage Isis supporter has admitted plotting a terror attack potentially targeting an Elton John concert on the anniversary of the 9/11 attacks.
Haroon Syed, from Hounslow, pleaded guilty to the preparation of terrorist acts between April and September at the Old Bailey after a last-ditch attempt to get his case thrown out failed.
The court heard how Syed attempted to buy weapons online, including a machine gun, handguns, a suicide vest and a bomb, and trawled the web to find crowded targets in London for the massacre.
