At least six people were killed and 17 others injured in a traffic accident in the southern Mexican state of Chiapas, officials said.

The accident happened on Monday when a truck hauling steel to a construction site lost its brakes and hit a line of vehicles waiting at a checkpoint outside Tuxtla Gutierrez, the capital of Chiapas, emergency services and state officials said.

Seven vehicles were completely destroyed in the crash and two people in one of the vehicles burned to death.

About 14,000 people, according to official figures, died in traffic accidents in Mexico last year. EFE
