Venezuela's President Hugo Chavez said Saturday he's returning his ambassador to Colombia following a diplomatic spat over weapons found in a rebel cache. Chavez told Ambassador Gustavo Marquez to return to Bogota 11 days after recalling him over Colombia's statement that the anti-tank weapons came from Venezuela, according to a report of The Associated Press. «Go back to Bogota, Gustavo,» Chavez said. «Go to work.»
