The Institute for Cuban and Cuban-American Studies at the University of Miami posted a report on the presence of Cuban military personnel in Syria. The report says the Institute
“ has received information that General Leopoldo Cintra Frias, Head of the Cuban Armed Forces, visited Syria recently leading a group of Cuban military personnel sent by Cuba in support of Syria’s dictator Assad and Russian involvement in that country.
“The Cuban military contingent will be primarily deployed in Syria manning Russian tanks provided to Assad by the Russians. It will also operate as a military force against Isis and other opponents of the Assad regime.” http://ctp.iccas.miami.edu/main.htm
The report has been picked up by a number of conservative news outlets, and Fox News secured a quote from an anonymous U.S. official who said that Cuban troops may have been training in Russia and may have arrived in Syria on Russian planes: //http://www.foxnews.com/world/2015/10/14/cuban-military-forces-deployed-to-syria-to-operate-russian-tanks-say-sources/
Note the word “may.” A few days later there was an official Cuban response. Foreign ministry official Gerardo Penalver “categorically denies and refutes the irresponsible and unfounded information regarding the supposed presence of Cuban troops in the Syrian Arab Republic,” a government statement said.
