Cuban President Fidel Castro will not travel to Spain for a summit of Spanish and Portuguese-speaking leaders, a Spanish government spokesman said on Thursday, according to Reuters. "Castro is not coming...The Spanish government has been informed of the decision," the spokesman said, adding that he did not know the reasons for Castro's decision. The two-day Ibero-American summit begins in the Spanish city of Salamanca on Friday. Spanish government officials had said previously they expected the 79-year-old Communist leader to attend the annual Ibero-American summit for the first time since 2000. A spokesman for the Cuban delegation could not confirm that Castro would not attend. Castro is notorious for only announcing at the last minute whether he will attend international events. The summit will focus on the economy, immigration and how to raise the Ibero-American group's international profile.
