Venezuelan President Hugo Chavez ordered tanks and thousands of troops on Sunday to the border with Colombia, accusing it of pushing South America to the brink of war by killing a top rebel leader on Ecuadorean soil. Denouncing Colombia's slaying of the rebel commander in a cross-border raid into Ecuador, Chavez said Venezuela will respond militarily if Colombia violates its border. He ordered Venezuela's embassy in Bogota closed. "Mr. Defense Minister, move 10 battalions to the border with Colombia for me, immediately - tank battalions. Deploy the air force," Chavez said during his weekly TV and radio program. "We don't want war, but we aren't going to permit the US empire, which is the master (of Colombia) ... to come divide us." Chavez called Colombian President Alvaro Uribe "a criminal" and branded his government a "terrorist state," likening it to Israel for its US-backed attacks on militants. In protest, Ecuador withdrew its ambassador from Bogota, ordered Colombia's top diplomat expelled and ordered the mobilization of troops to the border with Colombia. Ecuador's president, Rafael Correa, said Colombia deliberately carried out the strike beyond its borders. "There is no justification," Correa said Sunday night, snubbing an earlier annoucement from Colombia that it would apologize for the incursion. Correa said the rebels were "bombed and massacred as they slept, using precision technology." He said Colombia violated Ecuador's airspace when it bombed the rebel camp, which the Colombian military said was located 1.8 kilometers (1.1 miles) from the border. Colombian officials have long complained that Ecuador's military does not control its sparsely populated border, allowing rebels to take refuge. In a statement, Colombia said FARC "terrorists" including Reyes "have had the custom of killing in Colombia and taking refuge in the territory of neighboring countries." Ecuadorean soldiers recovered the semi-nude bodies of 15 rebels in their jungle camp, the corpses scattered around the site along with pieces of clothing, shoes, a refrigerator, guns and grenades. Soldiers stood guard at the camp, saying they also found three wounded women, who were evacuated by helicopter to be treated. One was a Mexican philosophy student injured by shrapnel, while the other two wounded guerrillas were Colombians, an Ecuadorean army officer said, speaking on condition of anonmyity because he was not authorized to talk to journalists. Ecuadorean officials found that there were two bomb attacks on the camp early Saturday, Lt. Col. Jose Nunez told reporters in the remote village of Angostura, where the bodies were found. Colombian commandos removed the cadavers of Reyes and one other rebel. Chavez called the raid "cowardly murder, all of it coldly calculated." He said the Colombians removed Reyes' body "as a trophy." "This could be the start of a war in South America," Chavez said. He warned Uribe: "If it occurs to you to do this in Venezuela, President Uribe, I'll send some Sukhois" - Russian warplanes recently bought by Venezuela. He called Uribe a "lapdog" of Washington, saying "Dracula's fangs (are) are covered in blood." The situation pushed already tense relations between Venezuela and Colombia to a new nadir, though cross-border trade has not yet been seriously affected. Chavez did not specify how many troops was sending to the border. A Venezuelan battalion traditionally has roughly 600 soldiers. "Undoutedly the recent actions on the part of Colombia and Venezuela's response raise the risk for armed conflict," said Miguel Tinker Salas, a Latin American studies professor at Pomona College in Claremont, California. "Although it is unlikely we will see military confrontations, what is clear is that Colombia has been pursuing a military solution to its own internal problem, ... drawing in Ecuador and Venezuela." Chavez has increasingly revealed his sympathies for the FARC, and in January asked that it be struck from lists of terrorist groups internationally. The leftist FARC has been fighting Colombia's government for more than four decades, and funds itself largely through the cocaine trade and kidnaps for ransom and political ends. Reyes was the FARC's key interlocutor with journalists and with foreign governments trying to mediate in the conflict, and thus the member of its leadership most vulnerable to being located, though eavesdropping or other intelligence. Chavez said that with US support, Colombian troops "invaded Ecuador, flagrantly violating Ecuador's sovereignty." US Embassy spokeswoman Suzanne Hall, in Bogota, declined comment on the possibility of US involvement, saying it was a Colombian government operation. In Texas, US National Security Council spokesman Gordon Johndroe said of Chavez's latest moves: "This is an odd reaction by Venezuela to Colombia's efforts against the FARC, a terrorist organization that continues to hold Colombians, Americans and others hostage." How exactly Reyes was killed was not immediately clear. Colombia's defense minister, Juan Manuel Santos, said Colombian commandos, tracking Reyes through an informant, first bombed a camp on the Colombian side of the Ecuadorean border. He said the troops came under fire from across the border in Ecuador and encountered Reyes' body when they overran that camp. After observing a moment of silence during his program Sunday in honor of the slain rebels, Chavez praised Reyes as "a true revolutionary," recalling he met the former trade union leader in Brazil in 1995. Chavez called Uribe's government "the Israel of Latin America," criticizing the Jewish state's military strikes on Palestinian terrorists. "We aren't going to permit Colombia to become the Israel of these lands," he said. "We have to liberate Colombia" from US dominance, he added. Colombia and Venezuela have been locked in a diplomatic crisis since Uribe sought in November to halt Chavez's efforts to mediate a prisoner swap. The FARC has since freed six hostages to delegates of Chavez, including four released last week. The FARC has demanded that a safe zone be created in Colombia to negotiate a swap of some 40 high-value captives, including former presidential candidate Ingrid Betancourt and three US defense contractors, for hundreds of imprisoned guerrillas.
