Guinsaugon, Philippines ? It was another day of frustration Wednesday with no sign of survivors as rescue workers tried to find an elementary school buried by a landslide under 100 feet of mud. Heavy rain forced troops to call off work, and a two-ton drill brought in by U.S. Marines sat idle with its braces missing.

Up to 300 children and teachers were thought to have been trapped in the school when a mountainside collapsed Friday after two weeks of heavy rain, burying the farming village of Guinsaugon in a 100-acre blanket of mud. Hopes for a miracle have focused on the school largely because of unconfirmed reports that survivors there sent mobile phone text messages to relatives shortly after the landslide.

But no one has been found alive since just hours after the disaster.

The official death toll reached 122 today, based on the number of bodies recovered, but officials fear it could surpass 1,000. At least 10 bodies were recovered Wednesday, but none near the school site.
