Lima: At least 15 people were killed and 19 others injured on Wednesday when a bus tumbled 700 metres down the side of a mountain in central Peru`s Ancash region, authorities said.
First responders have recovered 15 bodies, but "there are more, apparently", regional health director Cesar Fallaque told RPP Noticias radio, adding that the dead "are scattered across the slope".
All 19 injured passengers were initially taken to a hospital in Huaraz and were set to be transferred to better-equipped facilities in Lima, he said.
Four of the injured are in serious condition, Fallaque said.
The accident took place around 4 a.m. at a remote spot on the Conococha-Antamina highway, a police spokesperson said from the town of Chiquian.
Police are uncertain how many people were aboard the bus, she said.
The bus was travelling from Lima to Llata, a town in the Huanuco region, according to media reports.
