LOUISVILLE, KY. (AP/WDRB) -- Police in Wisconsin have evacuated homes in a Milwaukee suburb northeast of the Sikh temple where an unknown gunman killed six Sunday morning.
The evacuations are in Cudahy, which is about six miles from the temple in Oak Creek.
Police have roped off four blocks in a neighborhood with a mix of duplexes and single-family homes. They appeared focused on one house.
FBI agents were on the scene with an armored truck, a trailer and other vehicles. Milwaukee County sheriff's spokeswoman Fran McLaughlin says the department's bomb squad is also on the scene, but she has no details on why the unit was called.
Wisconsin police say the FBI will be handling the shooting case.
Oak Creek police chief John Edwards says the shooting is being treated as a domestic terrorism case and the FBI are better equipped to handle the situation.
Reports now say seven people are dead, including the suspected gunman. Police say three people have been injured, including the police officer that the gunman shot. Edwards says the suspect "ambushed" one of the first officers to arrive at the scene as the officer tended to a shooting victim. Edwards says the suspect shot the officer multiple times, before a second officer arrived on the scene and fatally shot the suspect.
Edwards says the officer that was shot is expected to survive.
Greenfield Police Chief Bradley Wentlandt says tactical officers have been through the temple, where shots were fired at about 10:30 Sunday morning.
He says they found four people dead inside the building, and three dead outside. One of the dead outside was the suspected shooter. Wentlandt says police do not believe multiple shooters were involved.
Authorities were called to the temple Sunday morning with a report of shots fired.
A spokeswoman for a Milwaukee hospital says doctors there are treating three victims of the shooting.
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.
President Barack Obama says he and first lady Michelle Obama are "deeply saddened" by the shooting. In a statement issued by the White House, Obama tells the people of Oak Creek, Wis., that "the American people have them in our thoughts and prayers." He says, "Our hearts go out to the families and friends of those who were killed and wounded."
The president says his administration will provide "whatever support is necessary" to those investigating the shooting.
Mitt Romney also expressed his sorrow about the shooting. He called it " a senseless act of violence and a tragedy that should never befall any house of worship." Romney said in a statement: "Our hearts are with the victims, their families, and the entire Oak Creek Sikh community. We join Americans everywhere in mourning those who lost their lives and in prayer for healing in the difficult days ahead."
