Authorities at Yakima airport in Washington evacuated the terminal and temporarily closed the airport Sunday when they found two training grenades inside a passenger's travel bag. However, mo one was hurt from the incident.

About 35 people inside the terminal were evacuated before bomb experts from the U.S. Army called in by police arrived to defuse the bomb, which contained no explosives.

Police arrested the 20-year-old man, a California-based soldier in civilian clothing. They released the man, whose name was not given, after charges of bringing a weapon inside a restricted area were filed.

The discovery of the grenades prompted airport authorities to close the facility for at least one hour. Passengers of one incoming flight were led to a different exit point instead of passing through the terminal. One flight to Seattle was canceled.
