Archaeologists in central Mexico have uncovered the bones of 12 children and adults who may have been buried 800 years ago.
The skeletons were discovered as the archaeologists supervised the installation of a new drain in an old neighbourhood about 120 kilometres north of the Mexican capital.
Most of the 12 skeletons are complete and their sexes will have to be determined in laboratory analysis.
AAP reports that the ethnic origin of the bodies is also yet to be determined, although archaeologists note that 800 years ago, the area was home to people from the Toltec and Olmec cultures.
Last April, another burial site with 17 skeletons, some 700-years-old, was found nearby.
