A frontal collision involving two buses transporting workers at a gold mine killed 16 people and injured 14 others south of the Arizona-Mexico border.

The crash happened at 3:36 a.m. Tuesday near the entrance to the Noche Buena mine, about two hours’ drive south of Lukeville Harbor along Federal Highway 2, according to the Sonora Attorney General’s Office.

The mine used the two buses to transport workers, it says in a press release. Pictures of the crash site showed that the two buses had crashed head-on and obstructed the two-lane road.

All 16 passengers traveling in the smaller of the two buses died on the spot, while the 14 traveling in the larger bus were transported to nearby Caborca, the attorney general’s office said.

Forensic personnel were given the task of inspecting the two buses after the crash. They identified the killed and wounded. Everyone involved in the crash is from Mexico, they added.

Survivors from crashes were hospitalized with major bruises and fractures.

The Noche Buena gold mine is owned and operated by the British-Mexican company Fresnillo plc. The company did not immediately respond to a request for comment.

They have operated the gold mine since 2012, according to the company’s website.
