Cuban President Raul Castro has denounced Washington's illegal training of so-called dissidents at the U.S. diplomatic mission in Havana. He said he recently told President Barack Obama of his concern that the U.S. government continues to carry out illegal activities in Cuba. The accusation came just after the Cuban president spoke of the possibility that the two countries could name ambassadors at the end of May, following the removal of Havana from Washington's list of state sponsors of terrorism. teleSUR
