A tour bus fell off Thursday morning while on an agricultural sightseeing trip near the Arizona-Mexico border, and more than 20 people were injured. The bus was carrying 52 people.

Yuma County Sheriff's Office spokesman Alfonso Zavala said the bus had been on a dirt road near a field and tipped over while attempting to turn on an embankment. The bus had been on a dirt field-access road and was trying to reach another road alongside a canal. But, it is too early to say what caused the crash.

Two of injured were flown to Phoenix Area hospitals. The others who were hurt were taken to a hospital in the nearby border town of Yuma, about 150 miles east of San Diego. Yuma Regional Medical Center spokeswoman Jenn Lotz said the facility saw 24 people between the ages of 27 and 82. She said one was transferred to a Phoenix trauma center, 16 were discharged and seven were admitted to the hospital.

The hospital spokesperson said that most of the patients suffered minor injuries, but no other details on their conditions were released.

Agriculture tours are quite common in Yuma, known as the "lettuce capital of the world". The bus crash occurred as the group was viewing a field of cabbage and celery crops, Zavala said.

The group was on a Field to Feast agriculture tour organized by the Yuma Visitors Bureau. The agency said in a statement it was "extremely sorry that this accident occurred."

The tourism office conducts the tours between January and March to showcase local produce. Tours include a narrated motor coach ride through farm fields, along with lunch made from locally grown food.

Anyone with information regarding the case is asked to contact the Yuma County Sheriff's Office at 928-783-4427.
