1.2 million in Japan told to use less water to help sinkhole rescue

Japanese authorities have asked 1.2 million people to cut back on showers and laundry to prevent leaking sewage from aggravating an operation to rescue the truck driver.

Rescue efforts have been severely hampered by unstable ground around the hole. The sinkhole and its vicinity remained cordoned off Thursday evening. Authorities say the initial cavity could be the result of sewage pipes underneath being corroded and gaping open.
