A lorry reportedly ploughed into a group of pilgrims in central Mexico on Wednesday, killing at least 16 people and injuring 30, local authorities say.
The accident took place when a group of 200 Catholics were taking part in a religious procession on the main street in the town of Mazapil in Zacatecas state.
The state government in a statement said that the lorry was carrying building materials when it hit the crowd, which was heading to a church.
An official in the state's civil protection agency said that the vehicle's brakes appear to have failed.
The truck drove off after hitting the crowd, local media said. An investigation into the incident is ongoing.
