People from Virginia to Pennsylvania are cleaning up and rebuilding after tornadoes destroyed buildings and knocked out power to tens of thousands of residents.

The storms Wednesday killed at least six people, including three in the tiny town of Waverly, Virginia.

At least two tornadoes blew through Pennsylvania, ripping off rooftops, collapsing homes and leveling an Amish schoolhouse in Lancaster County and damaging several buildings near Wyalusing.

A crew was already at work Thursday rebuilding the Amish schoolhouse, which roofer Derek Cummings said looked like it had been hit by a bomb. He said the 1,200-square-foot, one-story school could be rebuilt in a week. Pennsylvania emergency officials said they had no reports of deaths or injuries.
