OAK CREEK, Wisc. (CNN) - At least one gunman attacked worshippers at a Sikh temple in the Milwaukee suburb of Oak Creek, Wisconsin, on Sunday, leaving at least one dead and two wounded while police converged on the site.
Some people are believed to be trapped inside the Sikh Temple of Wisconsin, and at least one gunman may still be inside, Alderman Dan Jakubczyk told CNN.
"As far as I know, it is still an active situation," Jakubczyk said.
Carolyn Bellin, a spokeswoman for Milwaukee's Froedtert Hospital, said one of two men brought there from the incident was in surgery early Sunday morning, while the other was in the surgical intensive care unit.
There was no immediate comment from police in Oak Creek, on the south side of Milwaukee. But at least one body was visible lying in the parking lot, and Kathy Moran, a nursing supervisor at Columbia St. Mary's hospital in Milwaukee, told CNN that early reports suggested between eight to 20 people had been wounded.
Gurcharan Grewal, president of the Sikh Religious Society of Wisconsin, told CNN that he has heard from multiple people that there were wounded people still inside the temple and that there may have been multiple perpetrators. Police have sealed off the entire area, he said.
Grewal spoke to CNN from another Sikh temple about 20 miles away, where he said police were on the scene was well.
"We are really vigilant. We are really concerned," he said.
The temple has a congregation of 250 to 400, according to its website.
"I just want to say this temple was built a number of years ago and there have never been any problems with this temple," Jakubczyk said. "They've been a plus to this city and to my district."
