Four Cuban exile residents of Miami were detained on the island and accused of planning "terrorist actions," Havana authorities said Wednesday.

In a statement published by Communist Party newspaper Granma, the Interior Ministry said the men were arrested April 26 and alleged their targets were military.

"They intended to attack military installations with the objective of furthering violent actions," the statement said. "To such ends, since mid-2013, three of them had made several trips to the island to study and carry out their plan."

The statement named the detained men as Jose Ortega Amador, Obdulio Rodriguez Gonzalez, Raibel Pacheco Santos and Felix Monzon Alvarez.

It said they were operating under the direction of others in Florida purportedly linked to Luis Posada Carriles, who is alleged to have been behind a 1976 airliner bombing that killed 73 people aboard a flight bound for Cuba.

The Interior Ministry said it was reaching out to U.S. authorities to investigate.

An official at the U.S. Interests Section, which Washington maintains in Cuba instead of an embassy because the two countries do not have diplomatic relations, had no immediate comment.

Cuban officials did not immediately respond to a request for further details about the alleged plot.
