KEY LARGO, Fla.—A wooden boat carrying hundreds of Haitian migrants in a suspected human smuggling operation ran aground in shallow water in the Florida Keys, where 163 people swam ashore and many needed medical attention, federal authorities said.
The boat teeming with people listed sharply to its side near Ocean Reef Club in Key Largo, not far from where another boat carrying 176 Haitians was stopped in January.
