An Amtrak train carrying over 200 people derailed in Missouri on Monday afternoon while traveling from Los Angeles to Chicago, the company confirmed.
The accident happened around 12:40 p.m. near Mendon, Missouri, after the train collided with a truck that "was obstructing a public crossing," Amtrak said in a statement published on its website. The train had approximately eight cars.
"Local authorities are currently assisting customers," the company said. "Our Incident Response Team has been activated, and we are deploying emergency personnel to the scene to help support our passengers, our employees and their families with their needs."
Pictures from the scene posted to Twitter by passenger Dax McDonald showed dozens of passengers helping each other climb out of the overturned train through windows.
PEOPLE has reached out to local authorities for updates. Amtrak did not reveal how many people were injured.

During a press conference, Missouri State Highway Patrol Corporal Justin Dunn said there are at least three confirmed deaths as of Monday afternoon: two on the train and one in the truck that was hit.
In an update posted by the Missouri State Highway Patrol, officials added that there are "multiple injuries" and that all "injured and uninjured occupants of the train have been transported from the scene."
Passenger Robert Nightingale told CNN the train started to sway moments before it came off the track.
"It all happened like slow motion. It started to rock and, and rock, and then flicker, and then it just all of a sudden — all this dust was through my window," Nightingale told the outlet.
