The driver in Thursday’s van attack that killed 13 people in a tourist area of Barcelona may still be alive and on the run, Spanish police say.
They are hunting for Moroccan-born Younes Abouyaaqoub, now named by Spanish media as the suspected driver.
A man previously reported as the key suspect, Moussa Oukabir, 17, was one of five men killed by police after a later attack in Cambrils, west of Barcelona.
Police say the suspects had been planning more sophisticated attacks.
They said blasts on Wednesday in the town of Alcanar deprived plotters of bomb material so they carried out simpler attacks using vehicles.
Abouyaaqoub, 22, lived in the town of Ripoll to the north of Barcelona. Three people have been arrested in Ripoll and one person in Alcanar.
