Matamoros, Mexico:
Authorities in Mexico have said that a tractor-trailer collided with a truck carrying members of three families, killing at least 16 people in the nation's north.
Sergio Sisbeles, security spokesman for the northern state of Coahuila, said on Sunday that the accident occurred on Saturday evening on a non-toll highway between the community of Viesca and Matamoros.
The spokesman said that the people in the truck were from Matamoros and were traveling to a girl's traditional 15th birthday celebration in the rural community of Congregacion Hidalgo.
Mr Sisbeles said a preliminary investigation showed that the tractor-trailer crossed into the opposite lane and collided with the truck. The driver of the big rig fled the scene of the accident.
