Witnesses outside of a Sikh temple near Milwaukee say people inside with whom they have spoken are describing a hostage situation.
Police in suburban Oak Creek have not released any specific details about the shootings that took place Sunday morning. It was unclear how many people had been injured.
Authorities have responded with a dozen ambulances and tactical units. At least two people have been taken to the main trauma hospital in the area.
Sukhwindar Nagr, of Racine, says he called his brother-in-law's phone and a priest at the temple answered. Nagr says the priest told him that his brother-in-law had been shot, along with three priests.
Nagr says the priest also said women and children were hiding in closets at the temple.
