Quito - Thirteen people were killed and 28 injured when a bus overturned on a highway between the Ecuadorian capital Quito and the northern city of Ibarra, authorities said on Monday.
Twelve passengers died at the scene and another died later at a hospital, the governor of Imbabura province Paolina Vercoutere told reporters.
The accident happened around 20:00 on Sunday (01:00 GMT) near the town of Otavalo when the bus hurtled off the road and overturned, emergency services said.
In July, 14 people were killed and 30 injured in another bus accident in the centre of the country.
Deadly road accidents are common in Ecuador. A local non-governmental organisation estimates that at least 13 people are killed and 142 injured in road accidents every day, the vast majority as a result of human error.
