The suspects in the attacks in Barcelona and Cambrils were planning one or more bigger attacks than those that were carried out, police say, reported BBC. 

Catalonia's police chief said blasts in a town south of Barcelona on Wednesday deprived the plotters of bomb material, forcing them to carry out simpler attacks using vehicles to ram crowds.
