* Chavez's insults, dynamited bridges raise tensions

* Colombian military chiefs meet, no troop build-up seen

* Chavez says U.S. preparing for war in Latin America

BOGOTA, Nov 20 (Reuters) - Colombia will not be provoked into armed conflict with Venezuela despite its neighbor's aggressive rhetoric and dynamiting of two border bridges, Colombia's defense minister said on Friday.

"We will not be provoked. The insults bounce off us," Gabriel Silva said a day after Venezuelan troops blew up two wooden plank pedestrian bridges connecting the countries.

Venezuelan leader Hugo Chavez this month ordered his army to prepare for war after Colombia signed a military cooperation pact with Washington allowing U.S. troops greater access to its territory to run anti-narcotics surveillance flights.

Chavez says the agreement could set the stage for a U.S. invasion of oil-rich Venezuela, a claim that Washington and Bogota dismiss. He calls Colombian President Alvaro Uribe "a traitor" to the region for signing the deal.
