Residents in tornado-ravaged areas in Illinois and Indiana are grappling with the damage to their homes and neighborhoods after storms barreled through communities south of Chicago and left trails of destruction.

Officials in Merrillville, Indiana, said more than 200 buildings were damaged, including some that were destroyed. Downed trees and power lines blocked streets, and part of a high school's roof was ripped off. Cleanup crews were out working on Friday.
