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.
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.
The temple has a congregation of 250 to 400, according to its website.
