WASHINGTON, D.C.: Flash floods in the western state of Utah killed at least seven people Monday, state officials said. The disaster happened in the town of Hildale on the border with Arizona, the Utah Division of Emergency Management said on Twitter. A big wall of water hit people in their cars and washed them downstream, Hildale Fire Department Assistant Chief Kevin Barlow said, according to ABC News. The network said another six people were reported missing. Crews searched for missing people in the floodwaters but scaled back the operation at nightfall because conditions were still dangerous.
