Witnesses outside of a Sikh temple near Milwaukee say people inside with whom they have spoken are describing a hostage situation.

Police in Oak Creek a suburb of Milwaukee, have not released any specific details about the shootings that took place at the Sikh Temple of Wisconsin Sunday morning.

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.

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.

Current reports suggest there may have been four people killed and up to 30 injured. There are few details regarding who the shooter may be, but some reports suggest two people may be responsible.

Media reports say a local police officer "put down" one shooter suspected in the case. They also say an officer was shot multiple times at the scene, but they're expected to survive.
