The Zetas, one of Mexico's top drug cartels, may be splitting apart in an internal battle over trafficking turf, reports Fox News.
Reports in the Mexican media indicate that the Zetas may have split into two rival factions that are battling for control of the central states of Zacatecas and San Luis Potosi, as well as for parts of Yucatan peninsula.
Under President Felipe Calderon's administration, the number of drug cartels have skyrocketed to 25 from seven in 2006.
