Three people were killed and 26 others were taken to local hospitals when a bus carrying mostly teenagers crashed on an Indianapolis highway on Saturday afternoon.
It is thought a husband and wife are among the dead, and 26 people suffered injuries, some of them critical.
The accident occurred when the bus exited an interstate ramp and crashed into a concrete retaining wall, reports AP.
Investigators don't yet know what caused the crash about a mile from its destination, Colonial Hills Baptist Church.
According to the Daily Mail, 12 ambulances were required to transport the injured to hospital.
The Indianapolis Star reports that the third fatality was a teenager. One eyewitness told the paper that the bus was travelling at "a high rate of speed".
Carol Albright said: "It kind of pivoted on the nose of the bus and did a little bit of a twist. How it didn't hit another car, I don't know."
According to the Daily Telegraph, the bus was carrying 40 passengers, and the Indianapolis Fire Department had to free five people who stuck inside the bus after the crash.
