Volunteers gathered over the weekend to help clean up parts of Saga Prefecture flooded by torrential rain on Wednesday, but oil leaking from an ironworks is compounding their troubles.

In the town of Omachi, some 50,000 liters of oil used to cool iron is believed to have been washed away from the local plant run by Saga Tekkohsho Co.

The oil spread to residential areas and farmlands, damaging houses and ruining crops.
