A warning from the Transportation Safety Administration in Washington apparently caused a marked tightening of security measures at the major airports in the Dominican Republic. The Airport Security Forces and the Armed Forces were doubly vigilant after alerts that possible operatives from Al-Qaeda would use Dominican airports to infiltrate the United States. Oriental and Middle Eastern passengers were especially thoroughly checked and several were invited for interviews with security personnel. Dominican authorities received an extensive list of suspected terrorists’ names from the FBI and Interpol. During a recent conference in Cartagena de Indias, Colombia, intelligence officers received information of a network of Al-Qaeda that might be infiltrating its members into Latin America, and in the case of the Dominican Republic, university students from the Orient and the Middle East were mentioned as possible agents.
