One of the alleged Barcelona attack plotters has admitted a bigger attack was planned, say judicial sources.
According to BBC News, Mohamed Houli Chemlal was testifying in the Madrid high court, where the four surviving suspects are appearing.
He was injured in an accidental blast that reduced a house to rubble in the town of Alcanar last Wednesday.
Assailants went on to kill 15 people and injured more than 100 in a series of attacks in and around Barcelona the following day and early on Friday.
Eight members of the alleged cell are dead – two were killed in the Alcanar explosion, and six were later shot by police.
The last suspect was killed in a vineyard west of Barcelona on Monday.
