The cell behind the Barcelona van attack had planned to use explosives against monuments including the city's famous Sagrada Familia church, a suspect has told a Madrid court. The group's plans were scaled back when a house packed with bomb-making equipment blew up the day before.
The Alcanar explosion came the day before Thursday's Barcelona attack in which a van was driven at speed down the main Las Ramblas boulevard, killing 13 and injuring more than 100.
Two other suspects were killed in the Alcanar explosion, including Abdelbaki Es Satty, the Moroccan imam from the town of Ripoll thought to have been a radicalising influence on the suspects.
