Police in Wisconsin say one suspect has been "put down" outside a Sikh temple and they do not know if other shooters are inside the building.
Authorities were called to the temple Sunday morning with a report of shots fired.
Greenfield Police Chief Bradley Wentlandt says he doesn't know how many victims or how many suspects are involved.
He says a suspect fired at police and an officer put the man down. He says he has no word on the man's condition.
Wentlandt says it is an ongoing and fluid situation.
A spokeswoman for a Milwaukee hospital says doctors there are treating three victims of a shooting at a Sikh temple south of the city.
Froederdt Hospital spokeswoman Carolyn Bellin says the three victims of the shooting in suburban Oak Creek are all men. She did not have their identities or know why they were at the temple Sunday morning when the shootings occurred.
Belliin says one of the men is in the operating room, another is in a surgical intensive care unit and the third is being evaluated in the emergency room.
Belliin says the hospital is a level-one trauma center and is prepared to receive more patients from the shooting, but does not know if more will be on the way.
