Gas leak
Explosion rocks Wisconsin town in United States after natural gas main punctured by accident.
SUN PRAIRIE ( Wisconsin): An explosion rocked a Wisconsin community after a contractor struck a natural gas main in a downtown area filled with bars and other businesses, injuring two firefighters and a police officer, authorities said.
Firefighters and police officers responded to a reported gas leak, and an evacuation was underway when the blast happened on Tuesday, said Sun Prairie police Lt Kevin Konopacki.
He added that lives were likely saved as a result of the evacuation.
No deaths were reported but Konopacki said buildings would be searched in the Madison, Wisconsin, suburb of about 30,000 once the flames were out.
Firefighters were still battling flames more than three hours after the explosion.
The powerful blast around 7.15pm sent a plume of smoke and flames into the air.
Konopacki said the firefighters were taken to hospital while the officer was treated at the scene.
He said some civilians suffered minor injuries but none required hospitalisation.
WE Energies spokesman Amy Jahns said workers for a contractor apparently punctured a natural gas main, sending gas leaking into a building ahead of the explosion.
All 12 gas lines in the area were shut off by about 9.30pm.
The blast about half a block from City Hall appeared to be centred on the Barr House, a pub.
Authorities evacuated a radius just under a kilometre wide around the explosion and set up a shelter at Sun Prairie High School.
Steve Owen, 60, who owns Sun City Cyclery and Skates in downtown Sun Prairie, said he saw firefighters and police on the street and then the explosion happened.
He said the building across from his shop “literally lifted up”.
He said the force of the blast knocked him back in his chair and that he ran outside and saw a ball of fire.
