Eyewitness video shows police on the scene in California

Children are among four people shot dead in a horrific attack during a birthday party. The shooting broke out at a banquet hall in Stockton, California. 'Tragedy of this nature is unthinkable and it absolutely breaks our hearts to have loss of life and to have loss of life to children,' San Joaquin County District Attorney Ron Freitas said. Emotional footage from the scene showed groups of people hugging each other as police swarmed to the area.
