A bomb squad has issued the all-clear after examining two suspicious bags found in a cargo area at Boston's Logan International Airport, in the US state of Massachusetts, on Tuesday.
Authorities said a sniffer dog doing a routine security round appeared to pick up a suspicious scent while passing two duffel bags marked with a Nigerian address.
The Delta Air Lines cargo terminal was evacuated while the bags were examined.
State police said the packages were believed to contain bedding material and have been deemed not dangerous.
Airport spokesman Phil Orlandella said officials identified the people who brought the bags to the area and who shipped them.
Orlandella said passenger flights were not affected because the cargo building was about a mile away from passenger gates.
