BOSTON – A bomb squad has issued the all-clear after examining two suspicious bags found in a cargo area at Boston's Logan International Airport.

Authorities say a dog doing routine security on Tuesday 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 say the packages are believed to contain bedding material and have been deemed not dangerous.

Airport spokesman Phil Orlandella says officials identified who brought the bags to the area and who shipped them.

Orlandella says passenger flights were not affected because the cargo building is about a mile away from passenger gates.
