Local officials have reported that a van drove into a crowded tourist area of Barcelona, Spain on Thursday.

The white van mounted a sidewalk in Barcelona’s Las Ramblas district during the popular tourist district’s busiest month of the year. Police say that several people have sustained injuries from the incident, but have not confirmed any numbers.

Witnesses say that the van jumped a curb and was traveling quite fast, indicating that it certainly seemed intentional.

Police are now saying that the incident is “most likely” a terrorist attack.

The road has now been closed off by officials and emergency services has requested that local metro and train stations be closed.

In the last year, there have been several documented incidents in which terrorists use cars, trucks, and vans to drive into crowds and cause death, destruction, and fear. On Saturday, a U.S. White Nationalist drove his car into a crowd of counter-protesters, killing one and injuring several.

This is a developing story.
