Rear Adm. Eric C. Jones issued a warning statement Monday night as groups of Cuban immigrants said they planned to travel in boats filled with supplies to Cuba to show support for the Cuban protesters. South Florida has the country’s largest population of Cuban Americans. In Miami, Cuban social media personalities posted Monday that they would make the 10-hour boat ride to Cuba to show support after rare street protests broke out over the weekend, the Miami Herald reported. The influencers said they would bring aid — and guns — and urged people in Miami to offer up their boats. One group gathered Monday night at Pelican Harbor Marina near Miami’s North Bay Village, and people brought cases of bottled water, flashlights and boxes of canned Chef Boyardee pasta, the newspaper reported.
