TEZIUTLAN, Mexico (AP) - With dozens of people believed buried alive in mudslides, rescue workers struggled Thursday to reach remote towns in southern and central Mexico, where flooding brought on by more than a week of rain hE6as killed at least 218 people. Official death tolls soared throughout the day as rescue workers fought through mudslides for buried victims using everything from bulldozers to buckets to bare hands. Flooding sent rivers roaring over their banks across the southern and central half of Mexico. More than 157,000 people have been forced from their homes. In Mixun, a village in the mountains of Puebla state about 105 miles northeast of Mexico City, a mudslide buried 15 homes and a school. Ten people escaped but at least 40 others were believed trapped in the mud.
