Barcelona attack: New manhunt for suspected driver

So-called Islamic State (IS) said it had carried out the Las Ramblas attack, though it is not clear whether any of the attackers were directly connected to the group or simply inspired by it.

What is the timeline of events?

• Alcanar, Wednesday evening: An explosion rips through a house in the small town, 200km south of Barcelona. One person dies. Police chief Josep Lluis Trapero said it appeared the residents at the house had been "preparing an explosive device". A Catalan government official says a cell may have intended to use gas canisters in the Las Ramblas attack
• Barcelona, Thursday 16:50 (14:50 GMT): A white Fiat van drives down Las Ramblas in central Barcelona, killing 13 people and injuring scores. The driver flees on foot
• Vic, Thursday 18:30: Police find a second van, thought to be a getaway vehicle, in the town, 80km north of Barcelona
• Sant Just Desvern, Thursday 19:30: A car is driven towards officers at a checkpoint on the outskirts of Barcelona. They open fire. A man is later found dead in the passenger seat of the car with stab wounds. The dead man is not linked to the Las Ramblas attack, officials say, but investigations are ongoing. One theory is that the car was stolen and the man was killed by the carjacker, who is still at large
• Cambrils, Friday 01:00: A second vehicle attack takes place in the resort south of Barcelona. Police kill five terrorist suspects said to be linked to the Las Ramblas attack. They include Moussa Oukabir, 17, initially thought to be the Las Ramblas attacker. Police later say another man, Younes Abouyaaqoub, is being hunted
