South America's leftist leaders rallied to support Bolivian President Evo Morales after his plane was rerouted amid suspicions that NSA leaker Edward Snowden was on board and they demanded an apology from France, Italy, Portugal and Spain. The presidents of Argentina, Ecuador, Suriname, Venezuela and Uruguay joined Morales in the Bolivian city of Cochabamba ... to denounce the treatment of Morales, who warned that he would close the U.S. Embassy in Bolivia if necessary. Morales again blamed Washington for pressuring European countries to refuse to allow his plane to fly through their airspace on Tuesday, forcing it to land in Vienna, Austria, in what he called a violation of international law. He had been returning from a summit in Russia during which he had suggested he would be willing to consider a request from Snowden for asylum. Spanish Foreign Minister Jose Manuel Garcia-Margallo said Friday that his nation and other European countries were told Snowden was aboard the Bolivian presidential plane. He did not say who supplied the information and declined to say whether he had been in contact with the United States. Ecuadorean President Rafael Correa said that he and other leaders were offering full support to Morales following the rerouting of the plane, calling it an aggression against the Americas. Venezuelan President Nicolas Maduro protested alleged attempts by Spanish officials to search the Bolivian presidential plane and accused the CIA of encouraging several European countries to deny the presidential plane their airspace.
