An explosion at a chemical plant in western Japan on Sunday killed one worker and injured 17, including nearby residents, NHK TV channel reported.
The blast occurred at Mitsui Chemicals' Iwakuni-Ohtake facility in the Yamaguchi prefecture.
The explosion hit the adhesive plant shortly after 2 a.m. local time. A 22-year-old worker was killed and 11 others were injured.
The blast broke windows of about 270 buildings, including nearby houses. The hands and heads of six people were cut by broken glass.
