An explosion injured four men at a Japanese facility for storing unexploded bombs at a US air base in Okinawa on Monday, a fire official said, with their condition reportedly not critical. Japan Self-Defense Forces (SDF) members at the facility at Kadena Air Base were trying to wipe rust off items at the facility to re-assess if they were bombs, said local fire department official Akira Kamiunten. During that process there was an explosion that injured four male SDF members who were rushed to hospital, he told AFP.
