Ex-US ambassador sentenced to 15 years in prison for serving as secret agent for Cuba

Manuel Rocha, 73, will also pay a $500,000 fine after pleading guilty to conspiring to act as an agent of a foreign government

A former career US diplomat was sentenced Friday to 15 years in federal prison after admitting he worked for decades as a secret agent for Cuba, in a plea agreement that leaves many unanswered questions about a betrayal that stunned the US foreign service.

Manuel Rocha, 73, will also pay a $500,000 fine and cooperate with authorities after pleading guilty to conspiring to act as an agent of a foreign government. In exchange, prosecutors dismissed more than a dozen other counts, including wire fraud and making false statements.
