A teenager has denied responsibility for the Parsons Green terror attack which injured 30 Tube travellers.
He allegedly built and placed an improvised explosive device on a train and at or around Parsons Green train station which partially exploded.
Hassan, of Cavendish Road, Sunbury, Surrey, appeared at the Old Bailey before Mr Justice Haddon-Cave.
He appeared via video link from Belmarsh jail wearing a pink sweatshirt, and had short cropped hair and was clean shaven.
Hassan spoke only to enter not guilty pleas to both charges before he was remanded in custody for a two-week trial from March 5.
A further hearing was also set for February 23.
