Light streams through a window on emergency personnel after an explosion in a Milwaukee suburb demolished a church and damaged two homes Wednesday, injuring seven people, including three firefighters, authorities said. Rick James, a company spokesman from WE Energies, said a WE crew responded to a call around 12:30 p.m. that a gas line had been hit. James said he did not yet know whether natural gas caused the explosion.
