MEXICO CITY (AP) - Mexican President Felipe Calderon says 61 men who had been kidnapped by a drug cartel before soldiers rescued them were migrants.
    
Calderon said Monday that kidnappers working for the Zetas drug cartel were holding the men captive in the northern border city of Piedras Negras until their families paid a ransom.
    
Soldiers found the men Saturday at a safe house guarded by three of the alleged kidnappers.
    
Federal prosecutors say cartel workers intercepted the migrants outside a bus station in Piedras Negras and lured them to go with them by falsely offering to bring them into the United States for charges ranging from $600 up to $3,000.
    
Piedras Negras is across the border from Eagle Pass, Texas.
