 Rescuers in Japan are wading through mud, rock and debris in search of 24 people still missing after heavy rain triggered a massive landslide in the seaside city of Atami three days ago. Four people were killed. Police, firefighters and military personnel resumed rescue operations on Tuesday after they were suspended for the night on Monday. The operation heavily depends on rescuers working with their hands. The use of heavy machinery has been deemed too dangerous for many survivors who may be alive under the mud.
