Attack in Cambrils

​Hours after the violence in Barcelona, police killed 5 people in the nearby resort town of Cambrils. Spanish media reported they used a vehicle to injure six people and ram a police car. Police later said the attackers were wearing improvised explosive belts that were later detonated in controlled explosions. Both attacks are connected, police said.
