Seven killed in Wisconsin Sikh temple shooting
At least seven people, including a gunman, have died in a shooting at a Sikh temple in the US state of Wisconsin, police say.
The attacker "ambushed" a policeman at the scene, shooting him multiple times, before a second officer returned fire, killing the gunman, said authorities.
The shot officer was among three men critically injured in the attack in Oak Creek, suburban Milwaukee.
