JACKSON, Miss. (AP) — A casino bus full of tourists overturned in northwestern Mississippi on Sunday, killing three people and injuring several others.

The bus belonged to Harrah's Tunica and was carrying 43 people when it flipped over in a median at an intersection in Tunica, Tunica County spokesman Larry Liddell said.

Tourists on the bus were headed to the airport for a chartered flight to South Carolina, where many were from, officials said.

The bus was the only vehicle involved in the accident, which was still under investigation, Mississippi Highway Patrol Sgt. Leslie White said.
