Residents of a small northern Illinois town slammed by a powerful tornado were allowed to return to their homes on Saturday to assess damage, but safety concerns prevented them from staying for long.

Two people were killed and 20 others injured when a rare EF-4 tornado, the second highest intensity, tore through Fairdale, about 75 miles west of Chicago on Thursday. It damaged or destroyed almost every structure in the town of about 200 people.

Buses took evacuated residents on Saturday to assess damage and begin filing insurance claims, said a spokeswoman with the DeKalb County Sheriff’s Office. All residents would be escorted out of the area later on Saturday.

The DeKalb County Coroner’s office said on Friday two people, Jacklyn Klosa, 69, and Geraldine Schultz, 67, were killed in their homes.

Nobody was reported missing.
