The explosion of a World War II-era bomb at a Japanese airport this week has prompted the government to do a wider search for other possible unexploded bombs at airports that were targeted during the conflict.

An unexploded bomb detonated at Miyazaki Airport in Kyushu, Japan, leading to the suspension of flight operations.

An unexploded U.S. bomb from World War II that had been buried at a Japanese airport has exploded, causing a large crater in a taxiway and the cancellation of more than 80 flights but no injuries.
