The public prosecutor's office said today that the Syrians were detained November 14 and that the investigation is continuing.
Officials said the three have not asked for asylum, but they do not believe the Syrians are tied to any terrorist groups.
Spokesman Norman Serphos told The Associated Press that the three men came on an Insel Air flight from Haiti. No further details were available.
Officials said the Syrians had traveled from Europe then stopped in Brazil, the Dominican Republic and Haiti before entering St Maarten. It is unclear where they were headed.
