At least 13 people have been killed and dozens injured after a van in Barcelona ploughed into pedestrians before a gunman took hostages in a nearby bar.
Pictures and video emerging from the scene show armed police and paramedics rushing to Las Ramblas, a busy tree-lined promenade in the centre of the city.
Local media are reporting that Driss Oukabir, named earlier by police as a suspect, has been arrested.
Horrifying footage recorded at the scene shows dozens of victims lying injured on the pavement.
Police have confirmed that 50 people are hurt, with Catalonia’s interior minister Joaquim Forn saying it is ‘very possible’ that the number of dead will rise because of the ‘very serious’ wounds to victims.
Gunfire was heard at the Corte Ingles store in the area after police announced a ‘massive crash’ in Las Ramblas.
Officers were said to have negotiated with an attacker in a Turkish restaurant where hostages were being held.
A second van was found parked in the town of Vic some 50 miles north of Barcelona after police said it could have been used as a getaway vehicle.
The civil guard has said the van used in the attack was rented by Oukabir in the town of Santa Perpetua de la Mogada.
