SIOUX CITY, Iowa (AP) - Authorities blame arcing wires in an underground vault for causing a downtown Sioux City fire that led to explosions that blew manhole covers into the air.
The Sioux City Journal reports (https://bit.ly/2nhwPME) that MidAmerican Energy dispatched a crew after learning of the fire and blasts Wednesday evening. The workers isolated the problem and restored service to several customers that had lost power.
Fire officials say a pressure buildup from the fire caused the explosions. No injuries have been reported.
