Officials say three Claymore mine casings were found in a New Jersey woman's luggage as she passed through security at Terminal C on Tuesday morning.
The Transportation Security Administration says two of the three casings were packed with shrapnel but none featured explosives or detonators.
The woman told security officials she was attending explosives demonstration. She was permitted to re-book her flight to San Francisco and continue her trip without the weapons.
Claymore mines are land mines that discharge steel fragments.
