BOGOTA, Colombia Hundreds of Venezuelan troops moved Tuesday toward the border with Colombia, where trade was slowing amid heightening tension over Colombia's cross-border strike on a rebel base in Ecuador.
The Organization of American States scheduled an emergency afternoon meeting in Washington to try to calm one of the region's worst political showdowns in years, pitting U.S.-backed Colombia against Venezuela's leftist President Hugo Chavez and his allies. Colombian and Ecuadorean officials, meanwhile, traded accusations in the United Nations and the International Criminal Court.
The escalation of tensions was triggered over the weekend when Colombia troops crossed the border with Ecuador and killed Raul Reyes, a top commander of the Colombian FARC rebels who had set up a camp there.
Chavez, who sympathizes with the leftist rebels, condemned the killing and angrily ordered about 9,000 soldiers 10 battalions to Venezuela's border with Colombia. He warned Colombian President Alvaro Uribe that any strike on Venezuelan soil could provoke a South American war.
Colombia's defense minister said Monday that he would not be provoked into mobilizing troops in response.
President Bush said the United States will stand by Colombia and criticized Venezuela's government for making "provocative maneuvers." Colombia has received some $5 billion in U.S. aid to fight drugs and leftist rebels since 2000.
Retired Venezuelan Gen. Alberto Muller Rojas, a former top Chavez aide, told The Associated Press the troops were being sent to the border region as "a preventative measure."
Soldiers boarded buses and trucks at the Paramaracay base in central Venezuela Tuesday morning, and battalions also were moving out from the northern state of Lara, pro-Chavez Gov. Luis Reyes said.
The Venezuelan military has been tightlipped about troop movements. Venezuela's armed forces include about 100,000 troops, Muller Rojas said. Colombia's U.S.-equipped and trained military has more than twice as many.
Uribe said his government would ask the International Criminal Court to try Chavez for "genocide" for allegedly financing the Revolutionary Armed Forces of Colombia or FARC, the country's main rebel group. He cited a reference to a $300 million Venezuelan payment in documents found in a laptop the Colombians said belonged to Reyes.
The biggest losers from the killing of Reyes appeared to be the hostages that FARC rebels have held for years, pending a swap with rebel prisoners.
Ecuador and France said they had been communicating with Reyes, trying to secure a hostage release, when Colombia's air force crossed the border to bomb his jungle camp. Along with Reyes, 20 other rebels were killed.
"I'm sorry to tell you that the conversations were pretty advanced to free 12 hostages," Ecuador's leftist president, Rafael Correa, said in a nationally televised address. "All of this was frustrated by the war-mongering, authoritarian hands" of the Colombian government.
French Foreign Ministry spokeswoman Pascale Andreani confirmed that France was in contact with Reyes as well, and that "the Colombians were aware of it."
Colombia said documents in Reyes' laptop indicate that Correa's internal security minister met recently with a FARC envoy to discuss deepening relations with Ecuador, and even replacing military officers who might oppose that.
Publicly, there had been no indication of even preliminary progress in securing the release of any of the 40 hostages the FARC wants to swap for hundreds of jailed guerrillas.
Those hostages include three U.S. military contractors and former Colombian presidential candidate Ingrid Betancourt, a dual French national who has become a cause celebre in Europe.
Saturday's raid followed right on the heels of last week's release by the FARC of four hostages to Venezuela's justice minister, Ramon Rodriguez Chacin. The minister said the raid proved the "intent of the fascist Colombian government is to hamper the handover of hostages, because that is the path of peace."
Another victim of the crisis may be border trade worth $5 billion a year, most of it Colombian exports sorely needed by Venezuelans already suffering milk and meat shortages. Ecuador also depends on some $1.8 billion in trade with Colombia.
Venezuela said it would stop new exports and imports. At one closed border crossing, in Paraguachon, Venezuela, authorities stopped trucks lined up for about a half a mile Tuesday morning. But traffic was flowing normally at another crossing, in El Amparo, where a handful of Venezuelan troops stood watch as usual, the customs office was open and traffic passed freely.
Colombia's national police chief, Gen. Oscar Naranjo, made a series of shocking allegations based on documents in laptops he said were seized by commandos after the bombing at the camp. Among them, he said, was evidence that Chavez gave the rebels $300 million for some sort of "armed alliance."
He said other documents suggest Correa's administration was deepening its relations with the rebels, considered a drug-dealing band of terrorists band by the European Union and United States.
And the Colombian police chief even said some documents suggested the rebels were seeking to buy uranium, though he gave no details.
Both Venezuela and Ecuador expelled Colombia's ambassadors in the wake of the attack and dismissed the allegations as lies.
Venezuela later displayed the laptop of a slain drug trafficker, and said it implicates Naranjo in the cocaine trade.
Correa flew to Peru Tuesday as the first stop in a regional tour to rally other Latin American leaders against Colombia. Other diplomatic efforts to defuse the crisis were under way in Washington on Tuesday, where an emergency OAS meeting was scheduled.State Department spokesman Tom Casey said the United States supports Colombia's right to defend itself.
