500 residents of Iowa town homeless

The mayor of Mapleton, Iowa, said more than half of his city sustained some degree of damage after a tornado tore through the southwestern part of the small community Saturday evening. On Sunday, the National Weather Service confirmed the damage was caused by an EF-3 tornado. Mayor Fred Standa said he estimated 60 percent of the town sustained damage, and at least 20 percent of the community of 1,200 people was “completely flat.” More than 100 homes are reported to be seriously damaged.
