SHERMAN, Texas (AP) - Authorities say a charter bus ran off a highway overpass north of Dallas and crashed onto its side on a roadway below, killing at least 13.
About two dozen people are in area hospitals.
Sherman police Lieutenant Robert Fair says the bus carrying 55 people to Missouri from Houston may have blown a tire.
Police say 12 people died at the scene. Another died at a Dallas hospital, a Parkland Memorial Hospital spokesman told The Associated Press.
KHOU television reports the people on the bus were members of a Vietnamese church on a pilgrimage.
The Herald Democrat of Sherman reported the bus came to a rest on its right side in the northbound lane of an access road below U.S. 75.
Police say the accident happened just after midnight.
Northbound traffic on the highway was shut down as ambulances and helicopters used the roadway and median to ferry the injured to hospitals.
Sherman is about 65 miles north of Dallas.
