In an announcement Monday, the assistant secretary at the Department of Homeland Security in charge of aviation security, said US travellers can expect to see more scrutiny of toys as they pass through inspection gates at airports.
The New York Times has reported that there is "credible specific information" about terrorist tactics involving remote-control toys. However, there isn't intelligence on a specific plot, but DHS and TSA are taking the necessary precautions, including patting down children carrying remote-control toys.
Toy remotes have been used before by terrorists as a detonation device.
