Security officials in northern Mexico say 180 bodies have been recovered during an excavation of hidden graves in the city of Durango, located in the state with the same name.
Officials Tuesday said the bodies were unearthed from several sites and that the remains included those of 12 women.
In recent weeks, investigators also have unearthed 183 bodies from 40 mass graves in the northern state of Tamaulipas, where 72 Central American migrants were found shot to death last August. Mexico's Zetas drug gang is blamed for the Tamaulipas massacre.
