An explosion at a Wisconsin oil refinery has left at least 20 people injured.
The blast occured at the Husky oil refinery in the east end of the city of Superior, near the state border.
Witnesses reported a “sonic boom” at around 10am local time, with buildings shaking one mile from the scene.
Nearby buildings were evacuated as workers attempted to get upwind from huge plumes of smoke which billowed from the refinery.
One nearby worker told Duluth News Tribune: “It shook the houses all over. They felt it at Belknap Plaza.
“Tons of people were trying to get down there. They should be staying out.
“They had people evacuating, a lot of the contractors. They are trying to get upwind of the smoke.
“I’ve seen at least eight ambulances go in there and six fire trucks.”
The Superior Fire Department said “at least” 20 people have been injured.
Superior Fire Chief Steve Panger said: “There is a report of multiple casualties. Initial reports are at least 20 casualties transported. Multiple agencies have responded.”
