Mexico: 116 bodies found in mass graves

The toll of murder victims buried in mass graves in northern Mexico has risen to 116, with the attorney general blaming the atrocities on the brutal Zetas drug cartel.

Soldiers found the corpses last week in San Fernando in Tamaulipas state near the US border and initially unearthed 59 bodies. But the toll has since risen steadily.

The victims in Tamaulipas, one of the drug war's worst flash points, may have been killed after refusing to work for the Zetas cartel, according to media reports.
