March 4 (Bloomberg) -- Colombian President Alvaro Uribe said he'll seek criminal charges in an international tribunal against Venezuelan President Hugo Chavez for his alleged support of guerrillas in the region.

``I'll present charges to the International Criminal Court against Hugo Chavez for financing and sponsoring genocide,'' Uribe said on Caracol Radio today.

Colombia yesterday said it found evidence on the laptop of slain rebel leader Raul Reyes showing Venezuela had funneled at least $300 million to the Revolutionary Armed Forces of Colombia, known as the FARC. Human rights organizations accuse the group of massacring civilians, using illegal land mines, and committing terrorist bombings.

The laptop was seized March 1 when Colombia's military crossed into Ecuador to kill Reyes, the FARC's second-in- command. After years of international support for its counter- insurgency, Colombia finds itself diplomatically isolated in Latin America for taking the fight a mile into Ecuadorean territory.

Uribe lashed out at his neighbors, seeking to regain the moral upper hand by taking accusations against Chavez to an international forum and revealing the alleged contents of Reyes' computer to show Colombia is the victim of aggression from across its border.

Crimes Against Humanity

The court, based in The Hague, tries individuals accused of crimes against humanity, war crimes and genocide. Colombia and Venezuela signed the treaty that set up the court in 2002.

General Oscar Naranjo, head of Colombia's police, told Caracol Radio that documents from the laptop disclose FARC had been offered the opportunity to buy as much as 50 kilos of uranium at $2.5 million per kilo by an unnamed arms dealer.

General Naranjo said the computer files also indicated Ecuadorean Security Minister Gustavo Larrea had been in contact with Reyes in a bid to get President Rafael Correa involved in the release of rebel-held hostages to boost his political standing.

Larrea said yesterday he'd been in touch with Reyes only to try to negotiate the release of French-Colombian hostage Ingrid Betancourt, who has been in the FARC's hands since 2002, and that he did so with Uribe's knowledge.

The Colombian president has denied he had been told about the meeting.

`Deplorable Ties'

``Right now the government's focus is rightly on revealing to the world the deplorable ties between the FARC and the governments of Ecuador and Venezuela,'' said Alfredo Rangel, a former member of Colombia's state Security Council and head of a Bogota research group. ``Once the outrage over their border incursion dies down, Chavez and Correa will get their turn to be in the hot seat.''

Chavez and Correa denied the allegations and in turn accused Uribe's government of acting on the orders of the U.S. Ecuador and Venezuela both moved troops toward the border in response to the raid.

During a visit to Peru today, Correa said Colombia violated international law with the raid, and called on Latin American nations to take ``concrete actions.''

Stronger Military

Colombia, with bigger and better-trained forces, has little to fear, at least militarily.

``This won't come to warfare for a very simple reason: Chavez doesn't like to pick a losing battle,'' Rangel said. ``Once the outrage over their border. ``For its part, Colombia has no interest in opening a second front'' in addition to its war against the rebels.

Colombia's military is the most battle-tested, best- equipped and mobile force in the region, the result of four decades of warfare against the FARC. It has 260,000 active troops, more than double the combined strength of Venezuela and Ecuador's 115,000 fighters, Rangel said.

Colombia has spent about $38.6 billion on its military in the past decade, according to Rangel's Fundacion de Seguridad y Democracia research group. Since 2001, it has received $600 million in annual U.S. military aid and training.

President George W. Bush telephoned Uribe today to applaud his efforts against the rebels. He urged the U.S. Congress to approve a free trade agreement with Colombia, saying it is vital to the South American country's security.

OAS Meeting

Venezuela has spent $4 billion building up its military since 2004. It now has improved naval and air strike capabilities. Ecuador's military last saw action in a short- lived border dispute with Peru in 1995.

The criticism intensified as the Organization of American States said its General Assembly would hold an emergency session on the matter.

Brazil, Chile, Argentina, Nicaragua and Peru condemned the incursion, and Correa severed diplomatic ties with Colombia yesterday.

All of those countries except Nicaragua previously had declined to join Chavez's call to recognize the guerrillas -- branded as hostage-taking, drug-dealing terrorists by the U.S. and European Union -- as a legitimate army.

Correa began today a four-day tour of Latin America to drum up support against Uribe.

``What you have here is sovereignty versus transnational terrorism,'' said Ray Walser, a Latin America policy analyst at the Heritage Foundation in Washington. ``Sovereignty is sacrosanct in Latin America.''
