OAK CREEK, Wis. (AP) — An unidentified gunman killed six people at a Sikh temple in suburban Milwaukee on Sunday in a rampage that left terrified congregants hiding in closets and others texting friends outside for help. The suspect was killed outside the temple in a shootout with police officers.

Police called the attack an act of domestic terrorism, but did not provide any details about the gunman or suggest a possible motive. Oak Creek Police Chief John Edwards did not say whether he specifically targeted the Sikh community.
