Local media reported that the vehicle nearly fell down a mountainside but then came to a stop on an obstacle. The rescue work lasted nine hours. The bus was on its way from the port city of Tumaco to Cali, and according to press reports there was also fog at the time of the accident.
Serious traffic accidents are more common on the narrow, sometimes unpaved, mountain roads in the Andean regions of South American countries. The road conditions are often difficult and the buses are not always in good condition.
