At least 36 people have been killed and 12 others badly hurt after a bus ran off a highway and overturned in Ecuador on Sunday.
The bus was on a straight, well-paved strip of highway about 55 miles south of its destination, Quito, when the accident occurred at 3.20am.
"It seems like the driver fell asleep," said transit police spokesman Juan Zapata, though the cause of the crash remains under investigation.
Police said that driver Luis Mogrovejo, who died in the accident, had been at the wheel for at least seven hours.
Silvia Zumba, of the Latacunga police department, said the bus, from the Turismo Oriental line had left the city of Cuenca, with about 30 passengers and had picked up others along the way.
