SAN GIULIANO DI PUGLIA, Italy (AP) _ An earthquake jolted south-central Italy on Thursday, sending a nursery school roof crashing down on a class of preschoolers during a lunchtime Halloween party. At least 22 people were killed, nearly all of them children at the school.

Driven on by faint voices coming from the rubble, frantic rescuers worked through the night to save more than a dozen children who remained trapped after the 5.4 magnitude quake struck the Molise region, shaking the town of Campobasso and surrounding villages northeast of Naples.

San Giuliano di Puglia, a village of 1,195 people, was the hardest hit, with several buildings damaged. The ANSA news agency said 3,000 people in the region fled damaged homes.
