The gunman opened fire just before noon Sunday inside the St. Thomas Syrian Orthodox Knanaya Church in Clifton, in northern New Jersey.

Officials say some 200 people were attending a service inside the house of worship.

The New Jersey State Police and Passaic County law enforcement agencies say they are hunting for the gunman.

A law enforcement official says said the shooting may be a result of domestic violence.

Members of the church are mostly first-generation immigrants and their children from Kerala, India.
