Six people were killed and four others injured when a van carrying tourists and a truck with Bolivian tags collided in northern Chile, police said Sunday.

The accident, whose cause is being investigated, occurred just after 11:00 p.m. Saturday at kilometer 65 of the highway that links Arica, a city some 2,051 kilometers (1,274 miles) north of Santiago, to the capital.

The crash, which happened in the Cuesta del Aguila area, left at least one of the injured in critical condition, police said.

The majority of the people in the van were members of a family headed for a sightseeing trip in the Andes, while the truck was on its way to Arica.

The bodies of the four women and two men killed in the accident were taken to the coroner's office in Arica, police said.

A 5-year-old girl was among the injured people taken to the hospital in Arica, doctors said.

Olga Joo Benavidez, a 29-year-old accident victim, is listed in critical condition, hospital spokesmen said. EFE
