A bomb squad has detonated a piece of suspicious luggage that was smoking at the Seattle-Tacoma airport.

Port of Seattle spokeswoman Terri-Ann Betancourt said the luggage contained only a battery charger and electronics.

The incident early Thursday led to the evacuation of several hundred people in Concourse A and delayed two American and two Delta flights for about two hours.

Betancourt said the Port of Seattle bomb squad was called to check out suspicious luggage about 5:30 a.m. Thursday under the concourse where bags are screened.
