(CNN Spanish) –– The government of Peru said it is investigating the accident of a passenger bus on a highway that left "loss of life" – without detailing figures of people killed or injured – occurred on Monday in the Andean region of Huancavelica, in the south of the country.

The Superintendence of Land Transport of People, Cargo and Goods said in a statement that the bus had the corresponding permit to operate.

The accident happened around 1:30 a.m. (local time), when the bus fell down a ravine while traveling from the city of Ayacucho to the city of Huancayo, Danilo Palomino, commissioner of the San Miguel de Mayocc Police, told CNN.

Angie Cabrera, representative of the company Expreso Internacional Molina, told Canal N that the company is supporting the injured and will cover the expenses derived from the accident.

The district mayor of Anco, Manuel Zevallos Pacheco, told RPP Noticias that an avalanche was registered in the area almost a month ago.

Huanta police are helping to transfer the injured to hospitals, according to state news agency Andina.
