The attackers, who killed 16 people last August in Barcelona and the town of Cambrils, are said to have travelled to the French capital a week before their attack and had already rented a large truck to carry out their bomb plot, Spanish newspaper La Vanguardia reports.

According to the paper, an accidental explosion which occurred several days before the terror attack had been caused by explosives that were originally meant to be placed in the truck and set off in Paris. A source claimed that nearly 450lbs of TATP, an explosive favoured by the Islamic State terror group, had been present in the plotters’ demolished apartment.
