Bolivia offered asylum on Saturday to former U.S. spy agency contractor Edward Snowden, joining leftist allies Venezuela and Nicaragua in defiance of Washington, which is demanding his arrest for divulging details of secret U.S. spy programs. Snowden, 30, is believed to be holed up in the transit area of Moscow's Sheremetyevo international airport and has been trying to find a country that would give him sanctuary after he landed there from Hong Kong on June 23. Bolivian President Evo Morales had said earlier this week that he would consider granting asylum to Snowden. But he took a harder line on Saturday, angered that some European countries banned his plane from their airspace this week on suspicion it carried Snowden. "I want to tell ... the Europeans and Americans that last night I was thinking that as a fair protest, I want to say that now in fact we are going to give asylum to that American who is being persecuted by his fellow Americans," Morales said during a visit to the town of Chipaya. "If we receive a legal request, we will grant asylum," he said. Bolivia's Foreign Ministry was not immediately available to comment on whether a formal asylum request had been received. Venezuelan President Nicolas Maduro also offered refuge to Snowden late Friday, but the government said that by Saturday night it had not received any word back. Nicaraguan President Daniel Ortega said his country had received an asylum request and could agree to it "if circumstances permit." All three nations are members of the leftist ALBA bloc of countries that was forged by Venezuela's late Hugo Chavez and whose leaders often denounce U.S. "imperial" aggression. Russia has kept Snowden at arm's length, saying the airport's transit area where passengers wait between flights is neutral territory and that he would only be on Russian soil if he went through passport control. It was not clear whether the former U.S. National Security Agency contractor would accept any of the Latin American offers, nor how he would reach the countries if he does.
