SUPERIOR, Wis. (AP) The Latest on a Wisconsin refinery explosion that injured several people (all times local):
2:15 p.m.
Authorities have expanded the evacuation zone around a Wisconsin refinery that was rocked by an explosion and are now saying anyone within a three-mile (five-kilometer) radius should leave.
Douglas County authorities also say those in a 10-mile (16-kilometer) corridor south of the Husky Energy oil refinery in Superior should leave due to smoke coming from the site.
Evacuees are being told to gather at Yellowjacket Union at the University of Wisconsin-Superior or at Four Corners Elementary School in Superior.
It isn't clear how many people the evacuation order will effect. The refinery is in an industrial area, but there's a residential neighborhood within a mile to the northeast. The corridor downwind to the south is sparsely populated.
At least 11 people were injured in the Thursday morning blast. A spokeswoman for Essentia Health says one person was seriously injured, while another nine being treated at Essentia hospitals in Superior and nearby Duluth, Minnesota, have non-life-threatening injuries.
St. Luke's Hospital in Duluth received one patient who is in fair condition.
