At least 43 people have died and dozens were injured after a bus went off a cliff on a hairpin bend in rural Guatemala, tumbling 200m into a river at the bottom of a ravine, officials said.
Rescue workers said the bus, which plunged off a paved highway about 60km northwest of Guatemala City, was destroyed and more than 40 people were taken to hospitals for treatment.
Investigators do not yet know what caused the crash or what was the final destination of the bus, which was travelling south toward Guatemala City.
Rescue workers said conditions were dry and mostly sunny and that the bus was likely over capacity.
"The bus was overloaded," said Sergio Vasquez, a volunteer firefighter at the site.
He said 38 people died at the scene, including six children and 12 women. Five more died at hospitals, he said.
Local television said many passengers were vendors taking farm produce to market.
The government declared three days of national mourning.
