Six people were shot and killed by an armed gunman at a Sikh Temple just south of Milwaukee, Wisc., the Washington Post said.
A man entered the Sikh Temple in Oak Creek with an automatic weapon and shot and killed four people inside the building and two more outside, the Washington Post said. He wounded a police officer before he being shot dead by a second. Three other people were injured in the shooting.
The three injured civilians and the wounded officer were taken to Froedert Hospital in Milwaukee and are expected to survive.
Police recovered a semiautomatic pistol at the scene, the Washington Post said.
Initial reports of the shooting said there were multiple gunmen, but police later said the man killed was the only shooter, the Washington Post said.
According to the New York Times, the police have not yet released the identity of the man or established a motive. The FBI is currently investigating the shooting and are looking into the man's background.
The FBI is currently classifying the shooting as a domestic terrorist attack, the New York Times said. It is the first recorded act of violence target at Sikhs in Wisconsin.
"Right now, it's just a mass shooting," said a federal official to the New York Times.
Since the attacks on Sept. 11, 2001, there have been scattered reports of threats made against Sikhs across the nation, the New York Times said. Some people confuse them with Muslims due to their beards and colorful turbans.
