MEXICO CITY — A bus overturned in central Mexico after colliding with a trailer that detached from a truck carrying corn, killing 24 people and injuring five, Mexican authorities said Saturday.

The accident happened at midnight on Friday as the bus was leaving Tepic in western Mexico’s Nayarit state for Ciudad Juarez in northern Mexico. The wounded were being treated at a hospital in Zacatecas.

Juan Manríquez Moreno, coordinator of the Zacatecas National Guard, said in a video statement shared on social media that the truck’s trailer broke off on a highway. The passenger bus collided with the trailer and overturned on its right side.

Rodrigo Reyes Mugüerza, the secretary general of the government of Zacatecas, also shared a statement from the scene of the accident. “We send our solidarity and condolences to all the families and individuals who lost a loved one in this unfortunate accident,” he said.

He added that the highway where the accident occurred was closed as authorities secured the area. Authorities said they would soon release the names of the injured so families could find them.
