An explosion occurred at a Japanese military facility inside a US airbase in Okinawa, officials said, with local media reporting non-life-threatening injuries.
A defence ministry spokesman said they had received reports of an explosion at the Japan Self-Defence Forces (SDF) facility inside Kadena Air Base in the southern Japanese region.
Jiji Press and other local media said four injuries had been reported, but none were life-threatening.
Public broadcaster NHK said, citing unnamed defence ministry sources, that the explosion may have occurred at a temporary storage site for unexploded bombs, with officials trying to confirm the situation.
