The Islamic terror group Isis has claimed responsibility for the attack in Barcelona. It has not yet released a statement on a second van attack in the seaside resort of Cambrils on Thursday, in which seven people were injured. The Guardian reports that five suspected terrorists were shot dead in Cambrils as a result of the van attack.

An explosion at a house in the coastal town of Alcanar on Wednesday night is also thought to be related to the incidents in Barcelona and Cambrils. One person died in the blast, according to Sky News, while another was seriously injured.

Three men have been arrested in Alcanar and Ripoll in connection to the attacks, but police are still hunting for the driver of the van that crashed into pedestrians on Las Ramblas. He is thought to have fled the scene on foot.
