Isis has claimed responsibility for the terrorist attack in Cambrils, Spain, in an official communique.
It had already claimed the prior attack in Barcelona but put out an official statement later encompassing both atrocities, which police in Spain had been treating as linked.
It came as Spanish authorities announced they believed the cell behind the twin attacks in Cambrils and La Rambla, Barcelona, had been dismantled.
Police had been investigating a cell of between eight and 12 people after a van smashed into pedestrians in the Catalan city on Thursday afternoon, killing 13 and injuring about 100.
The driver fled the scene and later, in the early hours of Friday, a car ploughed into a crowd in Cambrils, about 60 miles away. Five terrorist suspects were shot dead—four by the same police officer.
One woman later died of her injuries, and several other people were injured.
