Spanish officials have confirmed that 13 people are dead and as many as 100 people are injured after a van struck a crowd in what police believe is a terror attack on the busy, tourist-filled pedestrian street called Las Ramblas in Barcelona, Spain. 

The white van drove into the popular shopping and food district Thursday afternoon, traveling 1,800 feet through the pedestrian area, according to Rac1, a Catalan radio station. The driver and another person fled the scene, Spanish newspaper El PaÍs reported. 

The Mossos d'Esquadra, the police force of the Catalan autonomous region, said it had arrested two people, including a man identified as Driss Oukabir, in connection with the attack. Oukabir, a Moroccan national living in Spain, reportedly rented the van used in the attack. The other arrestee has not been identified.

In what may be an unrelated incident, police said in a tweet that a driver had knocked down two officers at a highway checkpoint in Barcelona, USA Today reports.
