PUEBLA, Mexico (AP) - An earthquake destroyed homes, toppled church towers and            damaged other colonial-era buildings in central Mexico, killing at least 15 people and injuring            hundreds. President Ernesto Zedillo declared the state of Puebla a disaster area after the            magnitude 6.7 earthquake struck Tuesday afternoon. "It felt very strong. It was a jumping            movement," said Raimundo Villas, 20, an industrial engineer, who described how a chunk of            falling cornice crushed one man in the city of Puebla, 60 miles east of Mexico City. Mexico's            National Seismological Service said the earthquake was centered near Huajuapan de Leon, 80            miles south of Puebla.
