AlQa'dah 21, 1433, Oct 7, 2012, SPA -- Mexico's navy said it has captured a key regional leader of the hyper-violent Zetas drug cartel. Sunday's communique from the navy identified him as Carlos Carmona Caballero and it blamed him for a series of violent incidents in Veracruz state, though it does not specify them, AP reported. It said he was caught in a car Friday with four other men who were also detained. The Zetas have been involved in much of Mexico's drug war bloodshed in their battles with Mexico's other main drug organization, the Sinaloa Cartel.
