CHARLES CITY, Iowa (AP) — A tornado hit an area near the Floyd County fairgrounds in Charles City, destroying several buildings and damaging others. The Des Moines Register reports the tornado hit the fairgrounds and homes in the northeast Iowa city about 12:30 p.m. Monday. Craig Anderson, the fair board treasurer, says the tornado destroyed two fairgrounds buildings and severely damaged two others. Two buildings at the nearby Floyd County Ag Center also were destroyed. No injuries were reported.

DES MOINES, Iowa (AP) — Iowa voters are overwhelmingly white, but the state’s few black voters could play an outsize role in choosing the winner of the first contest among Democrats seeking to challenge President Donald Trump. The Iowa caucuses tend to draw the party’s most motivated voters, and this year Democrats say black voters are energized as seldom seen. That could give the candidate who rallies the biggest share of the state’s 2% black population a narrow victory in a crowded field.

MOSBY, Mo. (AP) — Some property owners who accepted a buyout from the federal government because their homes are prone to regular flooding say they’ve grown frustrated with the long wait times to get their checks. An Associated Press analysis of federal data shows the government has spent more than $5 billion over the past three decades on its flood buyout program, and the costs have been rising over the past decade. This spring’s Midwest flooding is likely to add even more homes to the buyout queue.

SIOUX CITY, Iowa (AP) — Two Iowa women shot during a convenience store robbery are recovering in a Sioux City hospital.
