At least two Chileans were among the nine people killed in a tourist bus accident in Lima, which also left more than 30 others injured, authorities said Sunday.

The deputy prosecutors on duty, Luz Peña and Jessica Santos, on Sunday oversaw the lifting of seven corpses from the slope of the San Cristobal hill, in Rimac district, where the double-decker open-top bus overturned.

Representatives of the Public Ministry said two of the deceased are Chileans, a man and a woman, according to the documents found in their belongings but that their identities had to be corroborated.

One person died on the way to the Arzobispo Loayza hospital and another while being attended to at the hospital's emergency unit, taking the total death toll to nine.

Among the more than 30 people injured in the accident were two Chileans, aged 16 and 30 years old, who have polytrauma and cranial trauma and are being treated at the Arzobispo Loayza hospital, health ministry officials told state-run agency Andina.

A spokesperson for the fire department had earlier said that another Chilean and a Canadian, in addition to seven children, were taken to the Bravo Chico, Arzobispo Loayza, Sabogal and Dos de Mayo hospitals.

The double-decker open-top bus of the Green Bus Company rolled downhill for about seven meters, after taking a group of tourists to visit downtown Lima.

During the accident, four people were thrown from the bus, and three others were crushed to death under the vehicle, a police spokesperson told RPP Noticias The victims' identities and the majority of their nationalities are currently unknown.

San Cristobal hill offers a panoramic view of Lima, and to get there buses usually leave from the Plaza de Armas, in the historic center, where many tourists come to see the Government Palace and the Cathedral of Lima.
