Incident Summary:

12/14/1976: Suspected members of the New World Liberation Front (NWLF) attempted to bomb the home of San Francisco Supervisor and acting mayor, Diane Feinstein in San Francisco, California, in the United States. The powerful bomb could have been lethal according to police; however, the bomb misfired (the detonator went off, but the bomb did not ignite), and thus, caused no damage or casualties at the Lyon Street home. NWLF claimed responsibility for the attack, but it is uncertain whether their claims were confirmed.
