Mexican officials say 16 people are dead and 30 injured after an out-of-control truck that lost its brakes slammed into a religious procession in central Mexico.

The government of the north-central state of Zacatecas said in a statement that the accident occurred in the town of Mazapil.

A heavy truck carrying building materials lost its brakes on the town's main street Wednesday afternoon. It slammed into a pedestrian procession of local Catholics.

Such processions are common in Mexico to celebrate a saint's day or special religious occasion. They often walk on roadsides to local shrines.

There was no immediate information on the condition of the injured.
