Twenty-nine people, including a child, were killed and more than 20 were injured when a bus plummeted from a cliff in Peru, officials said, in the country's third multiple-victim transport incident in four days.
The accident happened on a narrow stretch of the Carretera Central road around 60km east of the capital Lima.
A police spokesman told TV Peru there was a child among the dead and two among the injured.
There were 63 passengers on the bus.
A search and rescue effort was under way for possible survivors and to recover bodies, the police department added on Twitter.
The police spokesman said "recklessness" contributed to the crash, adding that the bus had been traveling "at high speed".
It hit a rock and plunged into an abyss around 200m deep, according to survivor accounts.
On Sunday, 14 people died when two boats collided on the Amazon river in Peru. An undetermined number remain missing.
Two days earlier, another bus fell into a ravine in the country's southeast, killing 17 people.
Road crashes are common in the Andean country due to factors including speeding motorists, poorly maintained highways, a lack of road signs and poor traffic safety enforcement.
