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.

New details have been released after seven people were confirmed dead in a crash involving a tour van near Yellowstone National Park on Thursday.
