At least 37 people were killed and dozens injured in Peru when a bus plunged into a 200m (650ft) deep ravine after a head-on collision. The incident happened in the early hours of Wednesday morning on a rugged stretch of the Pan-American Highway that connects Peru with Chile in the country's southern region of Arequipa.

Local media report that the bus was carrying 60 passengers when it smashed into a pickup truck on a curve, careered off the road, and fell down to the banks of the Ocoña River.

Bus crashes are a frequent occurrence in Peru, particularly at night on mountainous routes, attributed to poor road conditions, excessive speed, and inadequate safety signage.

The bus, operated by the Llamosas company, was en route from Chala, a town in Caraveli province, to Arequipa. Both drivers reportedly survived the crash, which occurred at kilometer 780 of the Pan-American Highway South.

Images from the scene show the wrecked bus at the bottom of the steep ravine, its windows shattered, body severely damaged, and the roof caved in. Local officials, including Waldor Llerena, the district mayor of Ocona, acknowledged the area's treacherous terrain and the history of similar fatal incidents.

Thirty-six fatalities were confirmed at the scene, while another individual succumbed to injuries in a hospital, according to Walther Oporto, Arequipa's regional health chief. Health officials reported that 25 individuals, including three minors, are receiving treatment for their injuries.

An investigation has been initiated, with the driver of the pickup truck taken into custody by the Public Prosecutor's Office. In 2022, more than 3,300 traffic fatalities were documented in Peru, underscoring ongoing safety concerns. The Pan-American Highway, stretching from Alaska to the tip of Argentina, remains the longest road accessible by motor vehicle in the world.
