At least six people died and 14 were injured in a Monday morning crash between a bus and a tractor-trailer in the northern Mexican state of Nuevo Leon, officials told Efe.

The incident occurred about 33 kilometers (20 miles) from the city of Monterrey, the state capital, according to the emergency services office in the municipality of Cienega de Flores.

Among those who perished is a 10-year-old boy, his mother and other people from the neighboring state of Coahuila.

The bodies of the victims were transported to the medical examiner's office at the Universitario Hospital by personnel with the Nuevo Leon Attorney General's Office.

According to initial reports, the driver of the truck was at fault in the crash, losing control of his vehicle due to a mechanical failure and crossing into the oncoming lane where he hit the bus belonging to Transportes Senda, which had departed from Ciudad Acuña, Coahuila.

As a result of the crash, the highway linking Monterrey and the northern border city of Nuevo Laredo was partially closed for several hours, causing a huge traffic backup in the southbound lanes. EFE
