Miami-AP -- Three dozen federal workers at the Miami airport have been taken to the hospital.
Officials say a strange odor caused some of them to suffer eye irritation and nausea.
A concourse was closed for about two hours after the Transportation Security Administration workers complained about the fumes at a security checkpoint.
Hazardous materials workers haven't been able to detect any chemicals or strange fumes. The investigation continues.
Officials don't believe there was any sabotage. They say early reports indicate carbon monoxide may be responsible. No passengers were affected.
