Five terrorists wearing fake suicide belts have been killed by police following the Barcelona attack, while three suspects are in custody.
Britons in the Catalonia capital and in the seaside town of Cambrils - the scene of a second attack in the early hours of Friday, around 70 miles (113km) west along the coast from Barcelona - described running for their lives after a suspected Islamist terrorist drove a van into crowds through the tourist hot spot of Las Ramblas.
At least 13 people died and more than 100 people were injured in the massacre, the deadliest attack in Spain since the 2004 Madrid train bombs in which more than 190 people were killed.
Catalonia president Carles Puigdemont said the five terrorists shot by police in Cambrils - where a car ploughed into pedestrians - were wearing fake suicide belts when they were stopped, and linked them to the earlier Barcelona attack.
There were also reports that investigators believe the eight-strong terror cell may have been planning an attack using gas canisters.
