At least 20 people died and 15 others were injured when a bus overturned on the Pan-American highway in southwestern Colombia.
The bus was traveling between the port city of Tumaco, on the southwestern corner of Colombia and Cali, 320 kilometers (200 miles) northeast, when the incident happened Saturday.
Captain Albertland Agudelo of Narino’s traffic police said: “Unfortunately, we have a death toll of 20.
Among the injured were a three-year-old girl and an eight-year-old boy.
Investigators are looking into “possible mechanical failures in the braking system,” Colonel Oscar Lamprea, regional director of traffic and transportation, said in a statement to reporters.
A preliminary report said the driver lost control after exiting a bend in a foggy area. It took rescuers from the police and fire department nine hours to straighten the vehicle, evacuate the injured and rescue the dead.
