A tour bus crash in southeastern Mexico killed eight Americans , two Swedes and a Canadian, as well as their Mexican guide, Mexican officials said Wednesday. The bus, which skidded and rolled off the road early Tuesday in Quintana Roo state, was transporting passengers from two US-based cruise ships to archeological sites. Along with the fatalities, the crash left 13 people injured, the Mexican officials said in a statement. US authorities earlier on Wednesday confirmed “multiple” American deaths in the crash.
