Guatemala's newly inaugurated president says Mexico's Zetas drug cartel sought to take over the drug trade in Guatemala by co-opting or killing local traffickers.
President Otto Perez says the Zetas offered deals for gangs willing to form part of their network, and killed those who refused.
The Zetas have been blamed for Guatemala's biggest drug-related massacre, the slaughter of 27 cattle ranch workers in May.
Perez says he is seeking to verify reports from ex-President Alvaro Colom that rival drug lord Joaquin "El Chapo" Guzman has been in Guatemala.
Perez told the Mexican television network Televisa Monday that the Zetas started moving into Guatemala about four years ago.
