Sorry About our Fake Bomb we planted : US tells Norway

U.S. officials apologized today for mistakenly leaving a fake bomb attached to an embassy vehicle in Oslo and causing a bomb scare that led to the evacuation of the U.S. embassy, Norway's royal palace and part of downtown Oslo.

The device had been placed beneath an embassy vehicle as part of a security drill and then mistakenly left there. It was spotted by security guards at the embassy's front entrance when someone tried to drive the vehicle onto embassy grounds just after 11 a.m. local time, triggering the evacuation of the embassy and the palace, the cancellation of an international children's soccer game nearby, and an interruption of nearby subway train traffic.

Deputy State Dept. spokesperson Patrick Ventrell confirmed that the device had been used in a previous drill and then forgotten.

"This morning at our U.S. Embassy in Oslo, Norway," said Ventrell, "Embassy security staff identified a suspicious device in an Embassy-owned vehicle and took appropriate precautions. Upon investigation, the device was determined to be a non-threatening training device previously used in an exercise."
