A bomb squad has issued the all-clear after examining two suspicious bags found in a Delta Airlines cargo area at Boston's Logan International Airport.
The facility was evacuated after a dog picked up a "suspicious scent."
Airport spokesman Phil Orlandella says the K-9 doing routine security on Tuesday indicated the scent by sitting down as he passed two duffel bags marked with a Nigerian address.
Orlandella called it a "low-level threat" but said authorities want to make sure the bags are fully examined.
He says officials have identified who brought the bags to the Delta cargo area and who shipped them.
The building, located on Harborside Drive, was evacuated. About 25 people were in the building before the evacuation.
Orlandella says no passenger flights were affected since the cargo building is about a mile away from passenger gates.
