An American couple who allegedly kidnapped their two sons and sailed to Havana last week sat in a Florida jail Wednesday after Cuba hastily handed them over to U.S. officials.

Cuban authorities turned over the family of four to the U.S. State Department and the FBI after CNN found them in Havana on Tuesday.

They arrived in Florida early Wednesday, where the two boys ages 2 and 4 will get a medical exam, according to Sheriff David Gee of Hillsborough County.
