Nine people have been killed and at least 50 injured in what police are now saying looks like an attack similar to the one that took place in Nice, France earlier this year.

Witness Emma Rushton described the scene to Sky News, “We heard a really loud bang and saw some of the Christmas lights to our left started to be pulled down. And then we saw the articulated vehicle going through people and through the stalls and just pulling everything down and then everything went dark.” She added, “There was lots of screaming, there were lots of people yelling.”

German police are saying this appears to be an attack though they have yet to identify a motive. Fox News is reporting that there were two people inside the truck:

The driver of the truck fled the scene but Reuters is now reporting a suspect has been arrested:

In November the U.S. State Department issued a travel warning for Europe, suggesting people be especially wary of areas where large crowds gather:

“Credible information indicates the Islamic State of Iraq and the Levant (ISIL the U.S. gov’t acronym for ISIS or Da’esh), al-Qaeda, and their affiliates continue to plan terrorist attacks in Europe, with a focus on the upcoming holiday season and associated events,” the travel advisory read.

The State Department urged travelers to avoid large crowds and exercise caution at tourist sites, festivals, large holiday events and outdoor markets. The agency also warned that these attacks can come with little or no warning

A similar attack took place in Nice, France on July 14th. A driver later identified as Mohamed Lahouaiej-Bouhlel killed 86 people by driving a truck through a crown of people watching fireworks on Bastille Day. Lahouaiej-Bouhlel was shot and killed by police while still inside the truck.

There was also a similar attack at Ohio State University last month.
