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.

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.

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.
