By Tomas Sarmiento CARACAS (Reuters) – Panamanian salsa star Ruben Blades, one of Latin America’s best-loved musicians, says he was not inviting foreign intervention in Venezuela’s deadly political unrest when he criticized both the government and protesters this week. Blades, 65, wrote on his website on Tuesday that President Nicolas Maduro’s administration and the opposition were “serving their own agendas” and failing to rein in more than a week of violence between security forces and protesters that has killed at least six people. Maduro, the successor of the late Hugo Chavez, said in a national speech on Wednesday that Blades had fallen for foreign propaganda against his government. “I love him … but this is an international lobbying campaign to bring artists every day saying something against the revolution, to create the conditions for a (foreign) intervention,” said Maduro, who then invited the “Amor y Control” singer to Venezuela.
