The central government and Hiroshima local governments appealed Wednesday a landmark ruling last month by the Hiroshima District Court that had recognized more victims of radioactive “black rain,” caused by fallout from the atomic bombing of the city, as eligible for support.

But the central government also said it would discuss expanding designated areas of support for the victims so that they would be able to receive assistance.

It was not immediately clear what kind of assistance would be offered or whether it would be the same as that received by victims in the current designated area.
