Cuba Arrests Four Miami-Based Exiles Accused of Planning Attacks

Cuba announced it has arrested four Miami-based Cuban exiles suspected of planning attacks on military installations to promote anti-government violence.

In a statement late Tuesday, Cuba's interior ministry labeled the suspects as terrorists. The government is linking the four men to Luis Posada Carriles, a Cuban exile and former CIA operative living in Miami who is wanted in Cuba and Venezuela over the bombing of a Cubana Airlines jet in 1976 that killed 73 people.

The four suspects were identified as Jose Ortega Amador, Obdulio Rodriguez Gonzalez, Raibel Pacheco Santos and Felix Monzon Alvarez.

Cuba said it would contact U.S. officials about the investigation, and said the four admitted to planning the attacks. Three of them had been traveling about the island since the middle of 2013 to plan its execution, according to the interior ministry statement published in official media.

On Wednesday afternoon the State Department said Cuba had not been in touch regarding the arrests and said they did not have details on the incident.
