Oct. 2 (UPI) -- A U.S.-made bomb dating back to World War II exploded at the Miyazaki Airport in Japan on Tuesday, damaging a taxiway, and causing a disruption in air traffic at the location.
An explosion was heard at about 8 a.m. local time, leaving a sinkhole at the taxiway connecting a parking apron and the runway, officials said. Investigators on the scene found bomb fragments and determined the explosion was caused by a long-dormant 500-pound U.S. bomb.
