Chavez threatens U.S. oil cut in Colombia dispute

Chavez, a leftist who says Washington is behind the charges, has never carried out previous threats to cut oil supplies to the United States, Venezuela's main customer.

"If there was any armed aggression against Venezuela from Colombian territory or from anywhere else, promoted by the Yankee empire, we would suspend oil shipments to the United States even if we have to eat stones here," he said.

"We would not send a drop more to U.S. refineries," he said to a roar of approval from thousands of supporters at a rally for his Socialist party.

Chavez, a former soldier and close ally of Cuba's Fidel Castro, is also angry with Bogota over a deal to allow U.S. troops access to a series of military bases.
