A suspect has told a Madrid court that the cell behind the Barcelona van attack had planned to use explosives against monuments including the famous Sagrada Familia.
According to Houli Chemlal, one of the four surviving suspects, the groups plans were scaled back when the bomb-making equipment blew up the day before.
Both him and Driss Oukabir have been charged with membership of a terrorist organisation and murder.
Of the other two suspects, Salah al-Karib has been detained for further investigations and Mohammed Aallaa was released on bail.
The explosion of the equipment was in a house in Alcanar only a day before the van attack on Las Ramblas last Thursday. These explosives were to be used for a much bigger series of attacks. The explosion killed two members of the cell.
