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.

Chinese and Italian tourists were reportedly among seven killed in a collision between a tour bus and a truck near Yellowstone National Park on Thursday. Eight others were injured when a Dodge Ram pickup truck and a Mercedes passenger van carrying 14 sightseers crashed on a highway in eastern Idaho, said US police. Both vehicles caught fire.

Idaho State Police say seven people died after a pickup truck and a tour van collided in eastern Idaho near Yellowstone National Park. The crash happened just before 7:15 p.m. Thursday on a highway near Henry’s Lake State Park. The state park is roughly 16 miles west of Yellowstone National Park.
