SEOUL, South Korea (AP) -- South Korea's military says it was a flock of birds that prompted it to alert journalists that it had detected an "unidentified object" flying near the border with North Korea.
The South's Joint Chiefs of Staff had said earlier that its radar found "the traces of flight by an unidentified object" on Monday over the central portion of the Demilitarized Zone that divides the two Koreas.
News reports say South Korea launched fighter jects and helicopters in response because it believed it could be a North Korean helicopter flying across the border into South Korea. The Joint Chiefs of Staff said it can only confirm that it deployed unidentified surveillance assets to find what that object was.
