Peruvian archaeologists have found evidence that a pre-Incan civilization, the Chimu of northern Peru, practised human and animal sacrifices.
The remains of 40 children and 74 llamas, sacrificed around 800 years ago, were found in the village of Huanchaquito.
The discovery also suggests possible links to other ancient civilisations in the region like the Aztecs, the archaeologists say.
