Guatemala — The Peten jungle, once known for its jaguars and Mayan  ruins, has fallen prey to a notorious Mexican drug gang that operates  from remote jungle ranches and has begun openly challenging Guatemalan  security forces for control of the roads.                
The struggle that's under way in this remote  region could help determine the fate of Guatemala, a fragile democracy  south of Mexico that's already under enormous pressure from narcotics  gangs. It's certain to affect Mexico, which is struggling to maintain  order against powerful armed gangs on its northern borders.
In a  fierce clash that began south of the famous Tikal ruins, the drug gang  known as Los Zetas, based in Mexico's northeastern border area and the  Yucatan Peninsula, was able to outgun local police by deploying armored  vehicles, bigger guns and far more ammunition. Then it fought a large  army patrol to a draw, losing vehicles and taking wounded but apparently  getting away with a stash of cocaine.            
The transformation of the once-pristine jungle into a no man's  land is the latest calamity to befall Guatemala, which has had a history  of military domination, a 36-year civil war and a genocide conducted by  the Guatemalan army against Mayan Indians some three decades ago.  Although the CIA helped overthrow a government in 1952, Guatemala's  newest drama is getting little high-level attention in Washington.
The recent confrontation between Los Zetas and the authorities began with a shouted warning from a bullhorn and a wrong turn.
Around  midday on Oct. 5, when police stopped a convoy of 16 or so big  double-cabin pickups and other vehicles a short drive south of the Tikal  National Park, an amplified voice from one vehicle barked a warning:
"We are Los Zetas! Let us pass. We don't want problems."
To  make their point, several men carrying assault rifles got out of the  vehicles and fired hundreds of rounds into the air in a deafening  display of firepower.
