Idaho troopers say they're still working with international authorities to notify next of kin following a fatal crash between a pickup truck and a passenger van carrying tourists Thursday evening.

A crash involving a bus and a truck has killed seven people in Idaho near Yellowstone National Park, according to state police. Newsweek has reached out to the Idaho State Police (ISP) via email Friday for comment.

The deaths of at least six foreign nationals in a fiery van crash in eastern Idaho are a reminder that many visitors to two of the busiest U.S. national parks, Yellowstone and Grand Teton, and nearby areas come from around the world.
