Authorities in the northern U.S. state of Wisconsin say a shooting at a Sikh temple Sunday morning in the city of Oak Creek, in the suburbs of Milwaukee, left seven people dead, including the gunman. Three people were wounded in the attack.
Police have described the suspect as a white male in his 40s, but have given no details or mentioned a possible motive. The local police chief said an officer exchanged fire with the gunman outside the temple and killed him.
Sunday evening, law enforcement officers extended their investigation of the shooting to a neighborhood in nearby Cudahy. They surrounded a duplex and evacuated several homes.
Officials say the Federal Bureau of Investigation is involved in the investigation because the shooting might be an act of domestic terrorism.
President Barack Obama said he was "deeply saddened" to learn of the shooting. He called the governor of Wisconsin, the mayor of the town and the trustee of the Sikh temple to express his condolences.
The Indian embassy in Washington says it has dispatched an Indian diplomat to visit the temple.
