Eyewitnesses rushed to social media to document the horrific moments after a hijacked beer truck plowed into a department store in the Swedish capital of Stockholm on Friday.

The crash on the busy downtown Drottninggatan Street left at least two people dead, according to Swedish Prime Minister Stefan Lofven who has since called the incident “an act of terror.”

Moments after the crash, people had shared videos on social media, showing people running from the area around the Ahlens department store.

As the commotion continued, videos posted on Twitter appeared to show police officers and authorities securing the scene.

Eyewitnesses also captured the striking images of heavy smoke coming from the area where the truck crashed into the department store.

People in nearby buildings took videos of emergency crews spraying what looked like foam on the truck that had plowed into the department store.
