At least 42 people were killed and five injured when a speeding bus hurled over a cliff in northeastern Guatemala, rescue officials said.
Survivors said the driver had been drinking and was speeding when the bus plunged over a more than 100-metre high cliff in the early morning hours of Monday near the Mexican border, some 226 kilometres from Guatemala City.
At least six children were among the dead. Officials earlier said 34 people had died in the accident.
Two other bus accidents elsewhere in Latin America left 18 people dead, including at least 11 children.
In Argentina, at least 12 people were killed and 41 injured, most of them teenage students, when a truck slammed into a bus filled with schoolchildren on a trip in the north of the country.
Another six people, including a one-year-old baby, died and four were injured when a Soviet-era truck in which they were riding crashed down a slope in eastern Cuba.
