The 16th Street Baptist Church bombing was an act of white supremacist terrorism[1][2] which happened at the African-American 16th Street Baptist Church in Birmingham, Alabama, on Sunday, September 15, 1963. Three 14-year-old girls and an 11-year-old girl were killed.
Four members of a local Ku Klux Klan chapter planted at least 15 sticks of dynamite beneath the steps located on the east side of the church.[3]
Although the FBI had concluded in 1965 that the 16th Street Baptist Church bombing had been committed by four known Klansmen and segregationists: Thomas Edwin Blanton Jr., Herman Frank Cash, Robert Edward Chambliss, and Bobby Frank Cherry,[4] no prosecutions were conducted until 1977.
